Hello!
I finally feel finished with the V2 Buggy that I've been worki...ng 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.
Most of it can be printed in PLA but some parts require Nylon or similar.
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:

Optional but recommended:
Gyro: SkyRC Gc301 https://goo.gl/MvZxy6

Some hardware might depend on what shocks and rodends you use!
I've spent hours just on these notes so please let me know if something seems incorrect.
