[FTC]: Pre-Manufactured Parts?

Our team is wondering if we are allowed to use rollers from a sliding screen door as pulleys on our robot? Also are we allowed to cut down a stanley door hinge on the robot?

In the rulebook it says that you can use linear slides and lazy susans, which our team are taking full advantage of, but if you are going to use rollers, I would recommend making them yourself, or possibly using linear slides. I don’t think that door hinges are allowed

Okay thanks :slight_smile:
