Addressing the following:
TOLERANCES. The original tolerances overall are extremely generous, especially in the drive train- this results in wobble everywhere. To address this I include CV GEAR HOUSING, CV WHEEL HOUSING and FRONT_AXLE scaled up to 102% plus a WHEEL SPACER of 4mm. Using these (printed on a reasonably calibrated printer) eliminates wobble almost completely.
CHASSIS. All chassis parts are “joined” by TPU pieces, helping with torsional rigidity - EXCEPT B03 / B04 joint. Print B03.5 Center Front Joiner in TPU and insert - problem solved.
BODY MOUNT. To help with mounting some third party body (best is 1:10 scale) I created “Back Body Mount” and “Front Body Mount”. They screw onto the existing pieces using shorter M4 screws from front and back - see photo. To adapt to your own body you may want to raise the top faces. Top holes are made for M4 heat inserts. I printed them in TPU (hard) to absorb impacts ;-)
