This is a mostly 3D Printed Electric Skateboard designed for the MY4777 3D printing class. It uses about $280 in materials and takes 3-4 hours to build once everything is printed. It uses the Open Source VESC for the speed controller and 3 - 1500mah lipo batteries. The board itself was printed on the Gigabot X prototype using recycled ABS pellets. The rest of the parts were printed in Polycarbonate at 100% infill for strength. Future improvements include: Customizible truck mounts to fit any skateboard, 3D printed trucks, wheels and motor, intigrated single batteries in board itself instead of lipos, and waterproofing the electronics. The commercial "equivalent" to this skateboard costs at most $999, so this project could save you 72% over the real thing.
