The thread is already quite watertight by itself, some thick grease could do the trick i guess, but i think i’ll used a round flat piece of silicon foam dropped in the cap.
Below is the fusion file:
The trigger and wheel are held with piece of 1/4 inch aluminum tube.
and the slot at the top needs to be filled with transparent silicon.
Body and Body12 need to be acetone glued (if your plastic permits) it’s way better printed in 2 parts.
and this is the code i’m now using:
it’s dirty, but works fine… i got lazy to write something clean to make the leds blink when the mode is confirmed at the end of the setup. And the debugging lines are still in.
Also note, it doesn’t self calibrate yet… so when the hall sensors are glued, they might be in a slightly different position and the code is to account for it.
