I searched the Internet for anything related to 3D-printing model cars. I would like to 3D-print parts for the model car and assemble it much like model car kits that you buy in stores. The maximum size of objects to be 3D-printed is 8.9 inches long, 5.7 inches wide, and 5.9 inches high. I found working engines and transmissions on Thingiverse web site. I'll start with a simple generic car with working parts. Any suggestions? The Visible V8 engine is available but the Visible Chassis was discontinued a long time ago. I think that the Visible V8 and Visible Chassis were based on 1950s cars.
