I would like to share my progress with my electric skateboard so far. I am going all 3d printed on this one.

I can say at this point, Motor mount and gears are all 3d printed and proven to keep up after 40-50 km of use. It took a lot of experiments and designing to get it right. But they are pretty strong now. I even made the motor mount tilt adjustable!
You can see motor mount side here : https://www.instagram.com/p/BLtuLHWgm4o/ This is 24th revision of the design. It took a lot of tries to get it to this stage.
Now I am focused on loopkey and remote controller.
Loop Key: I made it using 2 x XT150 connectors. It has charging resistor with a pushbutton I made a sliding switch style enclosure for the loopkey. I plan to make a switch design that will automatically press against the resistor push button prior to actual connection. Demo video here : https://www.instagram.com/p/BLzQCchgoOg/ Video first shows startup without resistor and later with it.
Remote Controller: I made it with an Arduino Mini Pro & 2.4 ghz radio module. No failsafe yet, but I will add that too. Pistol trigger is made of linear potentiometer and spring mechanism. Spring is adjustable to set idle position at deadband area, pull to speed up, push to brake.

Let me know what you think! Cheers, Ahmet
