2019-01-20 Edit: Updated BuggyV2_Rearsusp_Gearcover 2019-01-19 Edit: Updated BuggyV2_rearSusp_HubA.stl. Added _Gears_MotorGear_lowratio and _Gears_SecondGearC_lowratio for higher speeds 2019-01-12 Edit: Updated the wheel adapters. Updated the main hub for front suspension. Hello! I finally feel finished with the V2 Buggy that I've been working on for over a year, on and off. This has been a huge project with many iteration so I appreciate any tips if you like this model! Pretty much everything is printable on this model, even the drivetrain. It uses steel driveshafts/dogbones but the rest is plastic and holds up quite well. It's currently rear wheel drive only, which is the way I like it. You can run it with 1-3S batteries assuming the rest of your hardware works with it. It's possible to run 3D printed rims and tyres, but also bought wheels if you print the adapters to 12mm Hex. I'll make sure to do "how to build" videos on my youtube channel youtube.com/c/mrcrankyfaceprojects so stay tuned for those. HOW TO BUILD:https://www.youtube.com/watch?v=dokiQfjEbto Most of it can be printed in PLA but some parts require Nylon or similar. Project video:https://www.youtube.com/watch?v=_tMlQ5GjjWY Printables: ~800g of filament. 57 unique printable parts. If nothing else is mentioned, part should work fine in PLA. These need to be printed twice: BuggyV2_Body_WingBracket BuggyV2_RearSusp_WheelshaftA(Print with Nylon) BuggyV2_RearSusp_WheelshaftB BuggyV2_FrontSusp_SteeringA BuggyV2_FrontSusp_UpperArm BuggyV2_FrontSusp_WheelShaftA BuggyV2_FrontSusp_WheelShaftB If running 3D printed tyres/rims, print these twice: BuggyV2_Tyres_Front(Print with Ninjaflex, low infill) BuggyV2_Tyres_Rear(Print with Ninjaflex) BuggyV2_Rims_Front BuggyV2_Rims_Rear If running 'real' RC tyres/rims, print these to suit: BuggyV2_RearSusp_12mmHexAdapter_0mmOffset BuggyV2_RearSusp_12mmHexAdapter_5mmOffset BuggyV2_RearSusp_12mmHexAdapter_10mmOffset Offset will depend on the offset of your rims, print one and test. You should print these in nylon to make them last, other plastics don't survive if you have a strong motor: BuggyV2_RearSusp_Gears_DiffB BuggyV2_RearSusp_Gears_DiffC I would recommend printing these with PETG, Copolyester or even nylon, PLA is unreliable for these parts: BuggyV2_RearSusp_Gears_DiffA BuggyV2_RearSusp_Gears_FirstGearA BuggyV2_RearSusp_Gears_SecondGearB BuggyV2_RearSusp_Gears_SecondGearC BuggyV2_RearSusp_Gears_Motorgear These are optional but recommended for bought rims: BuggyV2_RimWasher (Print one for each rim and use as a washer on the outside) This helps you push some bearings into place without damaging stuff: Tool_bearingmounter.stl BOM Hardware: Frame/braces 4x M3x16 Caphead 6x M4 nut 14x M4x10 Countersunk 2x M4x10 Caphead 5x M4x20 Countersunk(can be replaced with m4x10 Countersunk) 4x M4x20 Caphead Rear suspension/gearbox 2x 70-80mm shocks(I think used "80mm 283004" on ebay) 4x Suitable balljoints for the shocks(I think I used "MST 310037" that you can find on Ebay) 2x 56mm(pin to pin)/61mm(total length) dogbone driveshafts 10x 6700ZZ(10x15x4mm) bearings 1x M3x10 Caphead 12x M3x16 Caphead 5x M3x25 Caphead 4x M4 nuts 2x M4x10 Countersunk 2x M4x20 Caphead 2x M4x40 Caphead Front suspension 2x 70-80mm shocks(I think used "80mm 283004" on ebay) 4x Suitable balljoints for the shocks(I think I used 2x "MST 310037" that you can find on Ebay and two that came with the shocks) 4x Rodends to connect steering rack to wheelhubs(Ebay for "M3 Straight Plastic Rod Ends") 4x 6700ZZ(10x15x4mm) bearings 4x M3x10 Caphead 20x M3x16 Caphead 2x M3x25 Caphead 4x M4x20 Caphead Steering 1x M3x10 Caphead 1x M3x16 Caphead 2x Rodends to connect servo to to steering rack Body 3x M3x16 Caphead Glue(Epoxy works great(XTC 3D)) Summary: 14x 6700ZZ(10x15x4mm) bearings https://goo.gl/513NVk 6x M3x10 Caphead https://goo.gl/xwdHev (select length and amount) 40x M3x16 Caphead https://goo.gl/xwdHev (select length and amount) 7x M3x25 Caphead https://goo.gl/xwdHev (select length and amount) 10x M4 Nuts https://goo.gl/xcDVQH (select length and amount) 2x M4x10 Caphead https://goo.gl/eyJ11L (select length and amount) 10x M4x20 Caphead https://goo.gl/eyJ11L (select length and amount) 2x M4x40 Caphead https://goo.gl/eyJ11L (select length and amount) 16x M4x10 Countersunk https://goo.gl/4Uq19X (select length and amount) 5x M4x20 Countersunk(can be replaced with m4x10 Countersunk) https://goo.gl/4Uq19X (select length and amount) 4x 70mm shocks https://goo.gl/piVs7D 6x Suitable balljoints for the shocks https://goo.gl/qv9Ffb 6x Rodends to connect servo to to steering rack https://goo.gl/amRCYf 2x 56mm(pin to pin)/61mm(total length) dogbone driveshafts https://goo.gl/PyMGhA Glue(Epoxy works great(XTC 3D)) Electronics Any motor/ESC, I used Sky RC leopard 13T with supplied ESC. https://goo.gl/Enid86 Any receiver, I used Flysky FS-GT3C. https://goo.gl/VtsFLc Optional but recommended: Gyro: SkyRC Gc301 https://goo.gl/MvZxy6 Epic wheels for trashing around: https://goo.gl/17ij1y Some hardware might depend on what shocks and rodends you use!
