Re: Practical 3D printed parts

Our printer was really useful this year.

The banebots motor mount was 3d printed, the pulley that is on the banebots motor was 3d printed (it fits over the gear on that motor), the pulley on the shooter wheel was 3d printed, and the shooter wheel itself was 3d printed. We had made some shooter wheels out of HDPE, but as they were cut they would warp because of internal stresses from the manufacturing of the plastic. The 3d printed wheels were perfectly balanced and improved our accuracy.

The 3d printed big pulley was printed in 12 hours because we didn't want to wait for the order to come in. The little pulley was the most useful because of the gear-shaped hole in the back. Originally, we tried "modifying" the 4:1 P60 gearbox to become 1:1, but it was inefficient. The 3d printed pulley let us interface directly with no transmission relatively easily.
