From the research, it was quite obvious that the only real option was to create a generic-looking design that resembled the majority of Automatic Couplers. This V1 design has the Electrical Coupler above the Coupler Head. \n\nNote: this is a representation of an automatic uncoupler and not actually a automatic uncoupler.\n\nAs this is designed to be a fuctional magnetic coupler the design is designed to be robust and strong and therefor is a representation of a Automatic Uncoupler and not a 100% accurate match, but in model form I hope it looks realistic.\n\nTo repesent the coupler head a little more accurate I have arranged the magnets to be fitted in two arrangements, one protruding and the other recessed.  \n\nThese items are designed to be printed on a 3D Resin printer.\n\nMy biggest concern with this was the strength of a resin for something like a coupling, so the design was kept fairly simple to maximize the strength.

Ive added cavities for magnets and for short spokes, so that one disc can be mounted onto the next, using a male and a female half as one disc,  expanding the amount of layers and thus the effect we seek.\n\nthe two halves are counter rotating due to the screws one has to insert around the core piece, Ive created the cavities extremely close for both halves so that the magnets are very close to each other with only little material between the fixated magnets. \n\nsupplied a few adapter rings for allowing to to use multiple magnet sizes in the same print. you can use every hole or not, space them in even or weird uneven ways, i even supplied a hollow version if you'd like to test other things like metal weights or bearings in the holes rubber bands etc... you can use a hole version or a half version, double them up against each other, twist their timing, use a spacer (neutral disc and clams) and add another differently configged layer lol... nothing you cant config and test.\n\ntalking about spacers, i will add a center axis spacer as well so we can place disc layers at variable distances depending on the magnets strength used etc. if one could mechanize the way the discs move together, it could be like a magnetic gearbox, like adding more weight in discs dragging or braking or for switching to a heavier gear... also added a few support stand if anyone wanted to hook up a motor to the system for testing and demonstration purposes. added the magnet shapes that fit the cavities so you can use these forms when you are not filling the cavity with a magnet, this lessens resistance of air. added several clams or clips to lock halves, two halves, two holes, two halves with a center spacer...\n\nadded the balls for the 2 types of bearings, the outer ring bearing is a little squeezed for more speed. supplied the round balls for the center axis bearing, print as many as needed. fill up the cavities. [32-64] the entire project can be scaled up or down if so desired, allowing for more powerful, and bigger magnets still. or go a little smaller of course. included are several center axis, different lengths same diameter, some hollowed.\n\ni live off of comments, your likes and your tips. thank you for watching and reading.","imageAlt":"Modular Variable Magnetic Coupling - 3D printable model","url":"https://www.cgtrader.com/3d-print-models/hobby-diy/automotive/modular-variable-magnetic-coupling-concept","isCLDApplicable":false,"isSaleOffApplicable":false,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/aY8N4eFmfBoJppiigTcBx5tf/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/1.jpg","gridUrl":"https://media.cgtrader.com/variants/aY8N4eFmfBoJppiigTcBx5tf/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/1.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/hobby-diy/automotive/modular-variable-magnetic-coupling-concept","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":12,"name":".obj","is_native":false},{"id":51,"name":".stl","is_native":false},{"id":17,"name":".max","is_native":false},{"id":5,"name":".fbx","is_native":false}],"categorySlug":"hobby-diy","subcategorySlug":"automotive","categoryTitle":"Hobby \u0026 DIY","subcategoryTitle":"Automotive \u0026 Car parts","schemaImageUrl":"https://img-new.cgtrader.com/items/3127861/8827d9cd10/modular-variable-magnetic-coupling-concept-3d-model-8827d9cd10.webp","saleOffDiscount":0,"eligibleForSubscription":false,"subscriptionSubscribed":false,"subscriptionPotential":false}},{"id":"3716010","type":"listingItem","attributes":{"id":3716010,"title":" Death Star Tractor Beam Coupling Terminal for action figures ","price":5.5,"description":"Tractor Beam Terminal for 3.75\" or 6\" action figure displays and dioramas.","imageAlt":"Death Star Tractor Beam Coupling Terminal 3D print model 2","url":"https://www.cgtrader.com/3d-print-models/games-toys/toy/death-star-tractor-beam-coupling-terminal-for-action-figures","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/mnRx3UXTcQtsJvoMTk4Bhznd/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/Shapr%20Image-2022-10-19%20120558.jpg","gridUrl":"https://media.cgtrader.com/variants/mnRx3UXTcQtsJvoMTk4Bhznd/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/Shapr%20Image-2022-10-19%20120558.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/games-toys/toy/death-star-tractor-beam-coupling-terminal-for-action-figures","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":51,"name":".stl","is_native":false}],"categorySlug":"games-toys","subcategorySlug":"toy","categoryTitle":"Games \u0026 Toys","subcategoryTitle":"Toys","schemaImageUrl":"https://img-new.cgtrader.com/items/3716010/ced040078c/death-star-tractor-beam-coupling-terminal-for-action-figures-3d-model-ced040078c.webp","saleOffDiscount":30,"eligibleForSubscription":false,"subscriptionSubscribed":false,"subscriptionPotential":false}},{"id":"4605873","type":"listingItem","attributes":{"id":4605873,"title":"Universal Coupling","price":6.0,"description":"Universal Coupling / Joint.

Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure and display pressure in an integral unit are called pressure meters or pressure gauges or vacuum gauges. A manometer is a good example, as it uses the surface area and weight of a column of liquid to both measure and indicate pressure. Likewise, the widely used Bourdon gauge is a mechanical device, which both measures and indicates and is probably the best known type of gauge.\n\nA vacuum gauge is a pressure gauge used to measure pressures lower than the ambient atmospheric pressure, which is set as the zero point, in negative values (for instance, −15 psig or −760 mmHg equals total vacuum). Most gauges measure pressure relative to atmospheric pressure as the zero point, so this form of reading is simply referred to as \"gauge pressure\". However, anything greater than total vacuum is technically a form of pressure. For very accurate readings, especially at very low pressures, a gauge that uses total vacuum as the zero point may be used, giving pressure readings in an absolute scale.\n\nOther methods of pressure measurement involve sensors that can transmit the pressure reading to a remote indicator or control system (telemetry).","imageAlt":"3D print model Pressure gauge ball valve 3 8 in","url":"https://www.cgtrader.com/3d-print-models/miniatures/other/pressure-gauge-ball-valve-3-8-in","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/XVC2amc6d3XhWXJBXeNyXPe7/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/pg.6.jpg","gridUrl":"https://media.cgtrader.com/variants/XVC2amc6d3XhWXJBXeNyXPe7/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/pg.6.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/miniatures/other/pressure-gauge-ball-valve-3-8-in","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":149,"name":".bip","is_native":false},{"id":129,"name":".3mf","is_native":false},{"id":14,"name":".skp","is_native":false},{"id":51,"name":".stl","is_native":false},{"id":12,"name":".obj","is_native":false},{"id":null,"name":null,"is_native":false}],"categorySlug":"miniatures","subcategorySlug":"other","categoryTitle":"Miniatures","subcategoryTitle":"Other","schemaImageUrl":"https://img-new.cgtrader.com/items/3766682/6385136b6f/pressure-gauge-ball-valve-3-8-in-3d-model-6385136b6f.webp","saleOffDiscount":50,"eligibleForSubscription":true,"subscriptionSubscribed":false,"subscriptionPotential":true}},{"id":"189423","type":"listingItem","attributes":{"id":189423,"title":"Shaft Coupling - Metric - Reducers","price":3.0,"description":"\u003cp\u003eFile: Shaft Couplings Reducers.STL\r\nName: Shaft Coupling - Metric - Reducers\r\nMaterial: 27 grams ( 0.06 lbs) Infill = 12%\r\nSize: 72.56 mm (2.857\") x 75.56 mm (2.857\") x 30 mm (1.181\")\r\nResolution: 0.20mm\r\nLayers: 156 layers  Rafts: Yes  Supports: No\r\nPrint Time:  3 hr 29 min\r\nFunction:  Prints a set of six couplings to connect 3mm, 4mm, 5mm, and 6mm shafts together in any combination required.

In ducting systems—especially in HVAC, industrial exhaust, or ventilation setups—flexible joints are essential for reducing stress on rigid pipes, ensuring a longer system lifespan and quieter operation. Their flanged or clamped ends allow for easy installation and maintenance in various industrial and commercial environments.","imageAlt":"Flexible joint pipe ducting 3D print model","url":"https://www.cgtrader.com/3d-print-models/hobby-diy/mechanical-parts/flexible-joint-pipe-ducting","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/kw8gefjklxkpfgeir5j3kzv06iwm/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/untitled.5.jpg","gridUrl":"https://media.cgtrader.com/variants/kw8gefjklxkpfgeir5j3kzv06iwm/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/untitled.5.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/hobby-diy/mechanical-parts/flexible-joint-pipe-ducting","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":51,"name":".stl","is_native":false},{"id":null,"name":null,"is_native":false}],"categorySlug":"hobby-diy","subcategorySlug":"mechanical-parts","categoryTitle":"Hobby \u0026 DIY","subcategoryTitle":"Mechanical parts","schemaImageUrl":"https://img-new.cgtrader.com/items/6280830/d58372e38d/flexible-joint-pipe-ducting-3d-model-d58372e38d.webp","saleOffDiscount":30,"eligibleForSubscription":true,"subscriptionSubscribed":false,"subscriptionPotential":true}},{"id":"1992578","type":"listingItem","attributes":{"id":1992578,"title":"Best 3D printable Break-Away coupling","price":3.0,"description":"The attached STL files are my own design for a durable 3D printed paracord break away.

They either printed poorly or failed easily.  This design connects the ends very easily, but requires a good pull to separate.   This is usable for any cord, but was desinged for both 1/8\" and 1/16\" paracord.   Just pass the cord through he hole and knot the end.  With 1/8\" cord on the inner part work the knot in slowly.  I have printed and used this design to connect bracelets, necklaces, key chains.  Really could be used anywhere you want two items connected with a cord, but able to break free.  \n\nI print in PLA, but any plastic will do.  Each part prints very easy with the cord side down thus preserving critical features.  I'd suggest using a brim to maintain attachment to the build plate.  Using standard speeds and normal build height of 0.15, each part builds in about 5 minutes.\n\nIf you have any suggested tweeks or modified versions you could use, just message me and and I'd be happy

It is open when the ball's hole is in line with the flow inlet and closed when it is pivoted 90-degrees by the valve handle, blocking the flow.[1] The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status.[2] The shut position 1/4 turn could be in either clockwise or counter-clockwise direction.\n\nBall valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to gates and globe valves, but they lack the fine control of those alternatives, in throttling applications.\n\nThe ball valve's ease of operation, repair, and versatility lend it to extensive industrial use, supporting pressures up to 1,000 bar (100 MPa; 15,000 psi) and temperatures up to 752 °F (400 °C), depending on design and materials used. Sizes typically range from 0.2 to 48 inches (5.1 to 1,219.2 mm). Valve bodies are made of metal, plastic, or metal with a ceramic; floating balls are often chrome plated for durability. One disadvantage of a ball valve is that when used for controlling water flow, they trap water in the center cavity while in the closed position. In the event of ambient temperatures falling below freezing point, the sides can crack due to the expansion associated with ice formation.[3] Some means of insulation or heat tape in this situation will usually prevent damage. Another option for cold climates is the \"freeze tolerant ball valve\". This style of ball valve incorporates a freeze plug in the side so in the event of a freeze-up, the freeze plug ruptures, acting as a 'sacrificial' fail point, allowing an easier repair. Instead of replacing the whole valve, all that is required is the fitting of a new freeze plug.[4]\n\nIn the case that a ball valve is used for cryogenics or product that may expand inside of the ball, there is a vent drilled into the upstream side of the valve. This is referred to as a vented ball.\n\nA ball valve should not be confused with a \"ball-check valve\", a type of check valve that uses a solid ball to prevent undesired backflow.\n\nOther types of quarter-turn valves include the butterfly valve and plug valve and freeze proof ball valve.","imageAlt":"ball valve 1 2 in 3D print

I have found them very reliable and the magnets work very well. The ABS like resin is definately recommend for these when printing.\n\nIn 2023 I bought some Hornby Magnetic couplings for my Hornby MK2F coaches but they were not long enough, I was very impressed with the magnetic strength of these couplings on other rolling stock. I tried some Kadee couplings but the sag in the couplings was causing issues going over points etc. I looked at Hunt Couplings but wasn't that happy with the look of the coupling and wasn't sure how they would couple to my Hornby Magnetic couplings. This was beginning to frustrate me so I finally decided to see if I could develop a similar coupling to the Hornby Magnetic coupling that I could print and install magnets. I found 2mm x 1mm round magnets on eBay for about £4.50 (50 off) and I started to develop a coupling. \n\nMy biggest concern with this was the strength of a resin for something like a coupling, so the design was kept fairly simple to maximize the strength. I printed my first set with AnyCubic black resin and installed magnets, I made a few modifications before testing a whole rake of 6 coaches on a model layout. After about 2 hours of testing I had no failures and the performance was really good. I then bought some AnyCubic ABS-like resin which proved to be better than the standard resin.\n\nMagnets used: \n\nhttps://amzn.to/3WZoThF **(Amazon)** Associate Link\n\nPlease be aware that 3D printed couplings will not be as strong as injected molded couplings, with using these you will probably need spares on hand in case of any break. With the ABS-like resin I have had minimal failures but nothing is perfect.\n\nI have included a range of sizes as different rolling stock need different lengths (Please message me if you would like other sizes).\n    Files with 75 are 7.5mm, 85 are 8.5mm, 100 are 10mm and 115 are 11.5mm (Distances are measured from NEM socket to Magnet Face - see pictures).\nMagnets need to be glued in and you need to have the correct magnetic polarity for each magnet. This is very important for coupling together.\nThe examples in the pictures were printed on an AnyCubic Proton M3 3D resin printer.\nFor dimensional accuracy, I would recommend printing on a resin printer.\nAs mentioned I used AnyCubic ABS Like Resin.\n\nuse this link to join CGTrader and download my designs.\n\nhttps://www.cgtrader.com/designers/PJD1974?referral_id=3218445","imageAlt":"3D printable model OO HO Magnetic Pipe Couplings for NEM","url":"https://www.cgtrader.com/3d-print-models/hobby-diy/hobby-accessories/oo-ho-magnetic-couplings-for-nem-socket","isCLDApplicable":false,"isSaleOffApplicable":false,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/qhFSFswCZGSX8yEYcJXmJb4A/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/Magnet%201.jpg","gridUrl":"https://media.cgtrader.com/variants/qhFSFswCZGSX8yEYcJXmJb4A/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/Magnet%201.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/hobby-diy/hobby-accessories/oo-ho-magnetic-couplings-for-nem-socket","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":129,"name":".3mf","is_native":false},{"id":51,"name":".stl","is_native":false},{"id":5,"name":".fbx","is_native":false},{"id":12,"name":".obj","is_native":false},{"id":null,"name":null,"is_native":false}],"categorySlug":"hobby-diy","subcategorySlug":"hobby-accessories","categoryTitle":"Hobby \u0026 DIY","subcategoryTitle":"Hobby Accessories","schemaImageUrl":"https://img-new.cgtrader.com/items/4783481/ed521d393d/oo-ho-magnetic-pipe-couplings-for-nem-socket-3d-model-ed521d393d.webp","saleOffDiscount":0,"eligibleForSubscription":true,"subscriptionSubscribed":true,"subscriptionPotential":false}},{"id":"5568077","type":"listingItem","attributes":{"id":5568077,"title":"N4 Counting Cars Horny Mike","price":12.0,"description":"Notice: the colour is only for presentation and ideas for the painting, and the miniature has no materials.\n\n\n\nN3 Counting Cars Scott Jones\n\n\n\nNote: Please do not share these files for free or commercially under any circumstances!\n\n\n\n\n\nThe miniature was made in highly dense poly, checked, and there was no error in printing.\n\nThe model is available in several popular formats, including OBJ, STL (print-ready), and 3mf.\n\n\n\nThe figure was ready in 7 scales: 1:87, 1:64, 1:43, 1:32, 1:25, 1:24, and 1:18, but it is of sufficient quality up to 1:8.\n\n\n\n\n\nPlease do not hesitate to contact me for further assistance or information regarding this figure or the missing file.\n\n\n\nminiature, 3d-print, miniatures, Figurines, 3dp-Miniatures, Diorama, Figurine, Diecast, 3d-print-figures, 3dpminiatures, Patreon, Danny-Koker, American-cars, Mechanics, Counting-Cars, Kevin-Mack, Scott-Jones, Horny-Mike, Roli-Szabo","imageAlt":"danny-koker 3D print model N4 Counting Cars Horny Mike","url":"https://www.cgtrader.com/3d-print-models/miniatures/figurines/n4-counting-cars-horny-mike","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/w2Zp9akAiudtbWeduAXUr3Qy/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/4Horny%20Mike0000e2.jpg","gridUrl":"https://media.cgtrader.com/variants/w2Zp9akAiudtbWeduAXUr3Qy/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/4Horny%20Mike0000e2.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/miniatures/figurines/n4-counting-cars-horny-mike","isCgtVerified":true,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":51,"name":".stl","is_native":false},{"id":129,"name":".3mf","is_native":false},{"id":12,"name":".obj","is_native":false}],"categorySlug":"miniatures","subcategorySlug":"figurines","categoryTitle":"Miniatures","subcategoryTitle":"Action Figures \u0026 Statues","schemaImageUrl":"https://img-new.cgtrader.com/items/5568077/3538eddbf5/n4-counting-cars-horny-mike-3d-model-3538eddbf5.webp","saleOffDiscount":0,"eligibleForSubscription":false,"subscriptionSubscribed":true,"subscriptionPotential":false}},{"id":"6356156","type":"listingItem","attributes":{"id":6356156,"title":"American Couplers for Cars and Locomotives - H0 Scale","price":2.0,"description":"American Couplers for Cars and Locomotives which I use in my models.

Since then I purchased a fairly modern Hornby HST that was made in 2018, when I got it the NEM coupling was lower than the standard position for NEM sockets. As I wanted to switch to magnetic couplings instead of tension lock couplings I decided to modify my Buckeye coupling that I recently developed. \n\nAs you can see in the photos this coupling raises the height of the magnetic buckeye by about 4mm so it will couple with the other buckeye couplings I have developed. \n\nWhen you download this item you will get the buckeye couplings for the HST power car and the buckeye couplings for the coaches.\n\nThe Buckeye Coupling for the power car come in 4 length, measured from NEM socket to magnet face.

These are 8mm, 9mm, 10mm, 11mm and 12mm. These can be used on other rolling stock and not limited to the HST.

Color 1000 Base Ten Cube Montessori 82mm","price":2.0,"description":"**Two-Color 1000 Base-Ten Cube (82 mm) – requires only one color swap**\n\nThis is a redesigned version of the classic base-ten thousand cube used for math learning (Montessori, primary school, manipulatives).\nThe idea was simple: make a two-color version without wasting filament and without dozens of color changes.\n\n**Smart color split**\nThe model uses a clever geometry that creates:\n\n- thin outer walls,\n- a clean two-color split with one single filament change,\n- no infill and no supports.\n\nYou can print the two colors either with:\n- one manual color swap on a single-extruder printer, or\n- any multi-material printer (Bambu AMS, MMU, Prusa combo, etc.) — all walls are compatible and symmetrical.\n\n**Snap-fit panel system**\n\nEvery wall is connected using self-tightening slide-in clips.\nAll clips are mirrored, so every panel fits with every other panel — no need to track orientation.\n\nThe cube is sturdy once assembled, but you can still disassemble it if needed.\n\n**Educational use**\n\n**Perfect for:**\n- teaching base-ten system and place value,\n- visualizing 1000 unit cubes,\n- color-coding math exercises,\n- Montessori-style manipulatives,\n- homeschooling.\n\n**Why this version?**\n\n- minimal material usage\n- only shells, no infill\n- fast printing\n- clean two-color effect\n- printable on any FDM printer\n- strong but lightweight\n\n**If you print it, feel free to share your Makes!\n\nPrinter Requirements:\nA multi-color FDM printer (MMU/AMS combo system) is required.\nThe model is designed for two-color printing using separate filaments in one job.\nSingle-extruder printers cannot produce the intended two-color effect.**","imageAlt":"Two Color 1000 Base Ten Cube Montessori 3D printable
