Hardware
The STLs for the remote are available at https://www.thingiverse.com/thing:2800544
There you will find several parts:
- Case Bottom (with or without 18350 holder)
- Case Top (with or without 18350 holder)
- Trigger Mechanism
- Spring Arm
- Switches
Overall it's a relatively easy print, the case and spring arm prints without any support, the switches might need a little support while the trigger mechanism needs the most (but nothing too crazy).
The case is held together with 4 2.2mmx12mm screws and there is a slot for a wrist strap should you need it.
The trigger mechanism itself holds the skate bearing and 2 x 5x8mm magnets (5mm diameter). The magnets need to be of opposing poles and if you get it wrong the remote basically will work in reverse or only in one direction, some trial and error might be needed.
The mode switch (the one next to the OLED display) will need a tiny bit of the metal on the limit switch cut or bent off. Both switches need to be installed together with the printed parts, the metal lever of the limit switch needs to be adjusted a little to fit. Lastly, I use a dab of hot glue to hold both down.
