This was a summer project to create a one piece 3d printed electric longboard. Is your printer big enough? For those that can't print it all in one go, I'll upload files later of the board split in thirds. It is solid Ultem 1010 and engineered to hold 280 lbs. Still a work in progress though. The space on the bottom houses 2 x 4s Lipo batteries, 120a esc, and a 2.4ghz receiver. The bottom of the board is covered by a 3/16" aluminum plate that is fastened by 4xM4 bolts.
Printed on a Fortus 900mc
Print Time: 6 days
Used http://www.thingiverse.com/thing:545345 for the large spur pulley on the wheel. Printed out of Ultem 9085. Works really well.
Added deck split into 3 parts
Files for electric drive components coming shortly. Decided not to weld components to trucks. Instead I used set screws to bolt the mount on the truck. Lots of loctite needs to be used! Videos under How I Designed This section!
