Electric Longboard Drivetrain for RAM Trucks

This is a fully 3D-printed electric longboard drivetrain with a built-in idler system for RAM trucks (https://www.amazon.de/RAM-UB-Truck-Longboard-Achsen-Griptape/dp/B01CQOIMX4/ref=sr_1_1?ie=UTF8&qid=1490127213&sr=8-1&keywords=ram+trucks) that can be removed. I have tested this build on over 150 km and no belt skippage has occured during hard braking.

Make sure you have the same truck cross-sectional area.

I used http://www.thingiverse.com/thing:545345 HTD5, 90 mm 40T for the wheels. T
