Available more than one handle design (multiple shapes), each with its own benefit and feel.Ergonomic fit \u0026 side adjustment (epoxy putty)The ergonomic grip is shaped as shown in the pictures. Some handles are smaller than others—if needed, you can add epoxy putty on the side to keep your hand perfectly aligned for accurate shooting.Safety / accuracy rule (important)Test the handle in shooting first before any modification and before going on a fishing trip.

It does not degrade or warp significantly in freshwater or saltwater.• Benefits: It offers excellent UV resistance, prints easily, and results in a beautiful matte finish straight off the printer bed.• Drawbacks: Requires a hardened steel nozzle as carbon fiber is highly abrasive.\nASA (Acrylonitrile Styrene Acrylate) • Why it works: Often considered the superior, outdoor successor to ABS. It is highly resistant to both UV light and continuous water immersion. • Benefits: Extremely tough with a high heat tolerance so the handle won't warp if left in the sun on a boat deck. • Drawbacks: Tends to warp more than PETG, usually requiring a 3D printer with an enclosed build chamber.Nylon (PA) / Nylon Carbon Fiber (PA-CF) • Why it works: Nylon is virtually indestructible under mechanical stress and absorbs heavy recoil shocks without snapping. • Benefits: Maximum impact resistance, which is ideal for a high-tension speargun. • Drawbacks: Nylon is highly hygroscopic (it absorbs moisture from the air and water) which will cause it to soften and swell in the water.

You must coat the finished handle completely in marine-grade epoxy to make it 100% waterproof.\nCNC / Wood Milling (Precision for DIY \u0026 Workshop Builds)\nThis 3D model is designed for milling in hardwoods such as:\nPadouk, Iroko, Teak, Makore, Sapelli, Kosipo, Mahogany\nor any Category 5 wood that doesn’t have high checking tendency.\nMaterials \u0026 bonding\n• Bond strips with epoxy (marine-grade) for durability and stiffness\nFile package (for CAM / CNC)\n• Speargun body extension: STL\n• Accessories: DXF /STL / (3D print )\nNote: For wood , carbon fiber panels or stainless steel, you must adjust tooling parameters to your machine/operator setup.\n\nI do the fabrication in the CNC and finish by hand tools.\n\n#speargun #spearfishing #CNC #Neptonic #Ermesub #3Dprinting #hobby #DIY #customdesign #underwateradventure #fishinggear #spearfishingcommunity #precisioncraftsmanship\nSTL files list : \nhttps://www.cgtrader.com/products/ambidexterity-speargun-handle-2025 \n https://www.cgtrader.com/products/custom-roller-speargun-spear-length-140-cm \n https://www.cgtrader.com/products/speargun-with-band-elevated-140-spear-trigger-ermesub-back https://www.cgtrader.com/products/speargun-line-guide \n https://www.cgtrader.com/products/speargun-rhombus \nhttps://www.cgtrader.com/products/speargun-handle-left\nhttps://www.cgtrader.com/products/speargun-handle\nhttps://www.cgtrader.com/products/left-hand-speargun-handle\nhttps://www.cgtrader.com/products/speargun-line-guide\nhttps://www.cgtrader.com/products/speargun-handle-2a17aba1-82e2-429c-8fad-0ca6820e02f7\nhttps://www.cgtrader.com/products/trigger-line-release\nhttps://www.cgtrader.com/products/thin-head-speargun\nhttps://www.cgtrader.com/products/speargun-handle-grip-2025\n\n","imageAlt":null,"url":"https://www.cgtrader.com/3d-print-models/hobby-diy/hobby-accessories/special-left-handle-ar-grip","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/sr7xlmbfla7wozi1po6kwyd2szre/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/Untitled%20%283%29.jpg","gridUrl":"https://media.cgtrader.com/variants/sr7xlmbfla7wozi1po6kwyd2szre/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/Untitled%20%283%29.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/hobby-diy/hobby-accessories/special-left-handle-ar-grip","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":51,"name":".stl","is_native":false}],"categorySlug":"hobby-diy","subcategorySlug":"hobby-accessories","categoryTitle":"Hobby \u0026 DIY","subcategoryTitle":"Hobby Accessories","schemaImageUrl":"https://img-new.cgtrader.com/items/7197034/9fe2aab6e0/special-left-handle-ar-grip-3d-model-9fe2aab6e0.webp","saleOffDiscount":50,"eligibleForSubscription":false,"subscriptionSubscribed":false,"subscriptionPotential":true,"subscriptionTierBand":"essentials"}},{"id":"7236514","type":"listingItem","attributes":{"id":7236514,"title":" line winder ","price":6.0,"description":"spearfishing line winder in two different sizes\n\n3D printing settings\nuse material that can stand the seawater","imageAlt":"line winder","url":"https://www.cgtrader.com/3d-print-models/hobby-diy/hobby-accessories/line-winder","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/7m1ymetvb4ar5ow7lgv7p5de63jt/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/Dorchester3D.com_linewnder.jpg","gridUrl":"https://media.cgtrader.com/variants/7m1ymetvb4ar5ow7lgv7p5de63jt/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/Dorchester3D.com_linewnder.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/hobby-diy/hobby-accessories/line-winder","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":51,"name":".stl","is_native":false},{"id":222,"name":".mp4","is_native":false}],"categorySlug":"hobby-diy","subcategorySlug":"hobby-accessories","categoryTitle":"Hobby \u0026 DIY","subcategoryTitle":"Hobby Accessories","schemaImageUrl":"https://img-new.cgtrader.com/items/7236514/13eb294a12/line-winder-3d-model-13eb294a12.webp","saleOffDiscount":50,"eligibleForSubscription":true,"subscriptionSubscribed":false,"subscriptionPotential":true,"subscriptionTierBand":"essentials"}},{"id":"6929080","type":"listingItem","attributes":{"id":6929080,"title":"Ferei 180 - flashlight button ","price":10.0,"description":"Ferei headlight button\n\nThis button has been redesigned to replace the stock one.

You can make the programming or print them on a 3D printer. STL files are available for a small fee. I can ship the handle made by strong polycast to your location for a small amount of money. Contact me for any inquiries.\n\nYou will need to handle the CNC programming yourself. I've been doing this hobby since 2013, gaining more experience over time. I have worked with various woods and experimented with many design ideas since I have access to my friend's CNC.\n\nleft /right hand speargun handle, specially designed for spearfishing enthusiasts and wood speargun makers. Our ergonomic handle shape enhances your underwater experience, providing optimal grip and control. With centerline fixation and a smooth surface, it ensures precise alignment and maneuverability. Available more than one handle design (multiple shapes), each with its own benefit and feel.\nErgonomic fit \u0026 side adjustment (epoxy putty)\nThe ergonomic grip is shaped as shown in the pictures. Some handles are smaller than others—if needed, you can add epoxy putty on the side to keep your hand perfectly aligned for accurate shooting.\nSafety / accuracy rule (important)\nTest the handle in shooting first before any modification and before going on a fishing trip. Check:\n• grip comfort under recoil,\n• stable aim,\n• consistent trigger alignment.\nJoint alignment (critical)\nKeep the mortise \u0026 tenon joint centred at the trigger.\nDo not shift the tenon/mortise off-center, otherwise the shooting alignment can be affected.\nPrintable handle can be glued only if you use the correct type of adhesive as per material compatibility , small debris can be removed manually .\n\n \nManufacturing settings\nFor 3D printing a speargun handle, you need materials that balance structural strength, water resistance, and UV stability. Carbon-Fiber PETG (PETG-CF) and ASA are the best all-around choices. Nylon offers the highest impact resistance but requires a marine-grade epoxy seal to prevent water absorption.\nFor the best results, use at least 5 to 6 wall lines (perimeters) and 40–50% infill to maximize structural integrity.\n1. Carbon-Fiber PETG (PETG-CF)\n• Why it works: Carbon-fiber reinforced PETG is stiffer and stronger than standard PETG. It does not degrade or warp significantly in freshwater or saltwater.\n• Benefits: It offers excellent UV resistance, prints easily, and results in a beautiful matte finish straight off the printer bed.\n• Drawbacks: Requires a hardened steel nozzle as carbon fiber is highly abrasive.\n\nASA (Acrylonitrile Styrene Acrylate) • Why it works: Often considered the superior, outdoor successor to ABS. It is highly resistant to both UV light and continuous water immersion. • Benefits: Extremely tough with a high heat tolerance so the handle won't warp if left in the sun on a boat deck. • Drawbacks: Tends to warp more than PETG, usually requiring a 3D printer with an enclosed build chamber.\nNylon (PA) / Nylon Carbon Fiber (PA-CF) • Why it works: Nylon is virtually indestructible under mechanical stress and absorbs heavy recoil shocks without snapping. • Benefits: Maximum impact resistance, which is ideal for a high-tension speargun. • Drawbacks: Nylon is highly hygroscopic (it absorbs moisture from the air and water) which will cause it to soften and swell in the water.

Our ergonomic handle shape enhances your underwater experience, providing optimal grip and control. With centerline fixation and a smooth surface, it ensures precise alignment and maneuverability. Available more than one handle design (multiple shapes), each with its own benefit and feel.\nErgonomic fit \u0026 side adjustment (epoxy putty)\nThe ergonomic grip is shaped as shown in the pictures. Some handles are smaller than others—if needed, you can add epoxy putty on the side to keep your hand perfectly aligned for accurate shooting.\nSafety / accuracy rule (important)\nTest the handle in shooting first before any modification and before going on a fishing trip. Check:\n• grip comfort under recoil,\n• stable aim,\n• consistent trigger alignment.\nJoint alignment (critical)\nKeep the mortise \u0026 tenon joint centred at the trigger.\nDo not shift the tenon/mortise off-center, otherwise the shooting alignment can be affected.\nPrintable handle can be glued only if you use the correct type of adhesive as per material compatibility , small debris can be removed manually .\n\n \nManufacturing settings\nFor 3D printing a speargun handle, you need materials that balance structural strength, water resistance, and UV stability. Carbon-Fiber PETG (PETG-CF) and ASA are the best all-around choices. Nylon offers the highest impact resistance but requires a marine-grade epoxy seal to prevent water absorption.\nFor the best results, use at least 5 to 6 wall lines (perimeters) and 40–50% infill to maximize structural integrity.\n1. Carbon-Fiber PETG (PETG-CF)\n• Why it works: Carbon-fiber reinforced PETG is stiffer and stronger than standard PETG. It does not degrade or warp significantly in freshwater or saltwater.\n• Benefits: It offers excellent UV resistance, prints easily, and results in a beautiful matte finish straight off the printer bed.\n• Drawbacks: Requires a hardened steel nozzle as carbon fiber is highly abrasive.\n\nASA (Acrylonitrile Styrene Acrylate) • Why it works: Often considered the superior, outdoor successor to ABS.

This is the name of one of the types of spinners designed for sheer fishing in the summer and winter seasons. By its appearance, it resembles an elongated \"blank\", at the ends of which ordinary loops are soldered.\nToday, there are many lures that are trying to force the jig out of the fishing tackle market. However, experienced anglers remain true to the classics. After all, not many of the wobblers or jig heads can also successfully fish the range of depths of a certain area, as the jig does. The bait is able to handle this without too much trouble.\nPerfectly copes with fishing in a plumb line at any depth. Thanks to a thin body, it flies over long distances, where the asp lives. Suitable for fishing in the sea, and in fresh water, and in the summer from a boat, and in the winter from under the ice - this lure will significantly increase your chances of success.\nLength - 98 millimeters, weight 70g.\n\n**If you need another size - write.
