Print one of each part. Assemble charge controller, MintyBoost, and resistor circuit board. I added auxiliary LEDs to the charge controller for charging and fully charged modes. Note that the two LEDs on the light bar share a voltage drop resistor. Use a hot glue gun to mount the circuit boards and light bar. The case is 200 mm long.
