Download the STLs to print. I made some casing in PLA (0.2 layers, no supports) and in red resin (0.065 layers, 10x base layers @ 30 sec + 3 sec further exposure).

Once printed, thread the supports for the motor driver with an M3 tap and assemble the kit as follows:

1. TP4056
2. battery
3. driver

Use double sided tape to stick the motor to the top half of the casing.
