1:64 RC Hotwheels Car(s)
Can I fit all electronics under the body of a Hot Wheels car frame?
In early 2025, I removed the die-cast body of my Mystery Machine Hot Wheels car from the plastic undercarriage and brought it to a local lab that let me use their 3D scanner to perfectly map the shell so I could place components with confidence that it would all fit together in the end.
Once my parts arrived from Alibaba, I got to modeling them and placing them into the CAD assembly for optimizing the position. Separately, I assembled and tested the electronics, and all seems to be working. I have servo and bidirectional motor control!

Unfortunately, due to the size of the parts (they are tiny), my Ender 3 struggles to meet the tolerancing necessary for gears to mesh. This has been sidelined while I work on my VTOL.
