Minty Tank

Small remote control FPV tank built in out of an Altoids tin.

These prints worked for me, but may require some filing/trimming to get to work.

The insert piece prints as one piece but I then cut it roughly in half to separate the front
and back halves.

The hole spacing fixture can be used to help mark and drill the motor and idler axel holes
in the tin.

The holes in the tin insert for attaching the motor holder lid as well as the cross holes in
the drive wheels are oversize to allow using M3 metal thread inserts. I use my soldering
iron to insert them.


For the electronic I used an ESP32-Cam module, a wemos D1 mini motor shield, and a 5V BEC. I use a slightly modified version of the Scout32 software from that project. The modifications we mostly to allow me to use the I2C motor shield with the N20 motors.
