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.

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 and 11mm. Personally I think 9mm is about right, but your choice.\n\nThe Buckeye Couplings for the coaches come in 5 lengths, 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. They can also be used on the Hornby HST that was produced after 2021.\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. As with the Vacuum Pipe design I recommend you use ABS like resin or something similar, I used AnyCubic ABS Like Resin.\n\nMagnets used: 2mm dia x 1mm thick\n\nhttps://amzn.to/3WZoThF **(Amazon)** Associate Link\n\nResin used: \n\nAnyCubic ABS Like Resin Pro 2 https://amzn.to/4dVZoEU  **(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 also recommend you print these vertically with the buckeye at the top.\n\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":"Hornby HST 2008 to 2021 Magnetic Buckeye 3D print model","url":"https://www.cgtrader.com/3d-print-models/hobby-diy/hobby-accessories/hornby-hst-2008-to-2021-magnetic-buckeye-couplings","isCLDApplicable":false,"isSaleOffApplicable":false,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/bd4YmaxhghxX6DaZuUidGRb1/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/thumbnail_IMG_4529.jpg","gridUrl":"https://media.cgtrader.com/variants/bd4YmaxhghxX6DaZuUidGRb1/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/thumbnail_IMG_4529.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/hobby-diy/hobby-accessories/hornby-hst-2008-to-2021-magnetic-buckeye-couplings","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"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/5811325/16cf589254/hornby-hst-2008-to-2021-magnetic-buckeye-couplings-3d-model-16cf589254.webp","saleOffDiscount":0,"eligibleForSubscription":true,"subscriptionSubscribed":true,"subscriptionPotential":false}},{"id":"5748284","type":"listingItem","attributes":{"id":5748284,"title":"OO HO Model Railway Coach and Wagon Connectors Buckeye","price":6.1,"description":"These coupling are designed to fit between coaches or wagons as a semi permanent connection, I have also done these as magnetic couplings where you can easily disconnect your coaches or wagons.
