Polycord Pulleys

[Max Boord]

3d printed pulleys work well depending on infill and load. 179 used them to transfer load between the middle to front and back rollers and had to wrap them in duck tape to get enough friction to transfer the load effectively. on 4592 we ran 2 775pros on our intake with quite a bit of compression and found a need to replace a pulley or 2 every match due to cracking however this should not be an issue in most situations as most of ours where broken by hitting other robots and the middle CDF plank. The best solution we found was to run loads of them (i think we ran 7 to 11 depending on the revision of the intake) and be ok with running with a few missing/ broken.
