This 3D-printed RC car has some nice design elements
- Laser cut frame
- Simple 3D printed steering
- 3D printed tires
- Metal threaded inserts in the 3D printed parts to accept bolts (M3x4 knurled insert nuts)
- Vented body housing electronics
- 18650 battery pack
- Excellent build video
The 3D printed pieces are attached to the frame using bolts and threaded inserts that are heated. In some places bolts are used as axles (e.g. for the steering mechanism and the wheels). The build video shows the details very clearly. Some of the problems seen are the printed drive gear stripping and the bearing mount plastic melting at high speed.
