A simple design for a R/C car body and chassis that prints without supports (I'm serious...give it a try!). Snug fit between chassis and body with option to screw together with two self-tapping screws.

Designed to mount four N20 micro gearmotors (https://www.pololu.com/category/60/micro-metal-gearmotors) but openSCAD files can be modified easily for different motors/axles etc.

Includes cut-away for an on/off switch in the chassis and mounting holes for Pololu or similar mounting brackets (https://www.pololu.com/product/1086).

Printed in PLA on a Cocoon Create Touch (Wanhao Duplicator i3 plus clone) using a brim for the body. STL files are oriented correctly for printing without supports. I know it looks impossible to print without supports but it worked fine for me so give it a try.
