Every year there is a question or three about using 3D printed parts.
This years question is about printing HS bearings, from Seth an event partner. Since HS bearings have been out of stock most of the season, can they be printed? https://www.robotevents.com/VRC/2021-2022/QA/993
The answer is:
Ok Seth, ball is in your court, ask the question again but make sure you reference the rules (and the answer has the rule list to reference)
