Inspired by recent posts on wiring and programming, I figured I’d make a post on mechanical lessons learned through failures, carnage, and possibly some uncontained rapid disassembly.
I guess I’ll go first. We needed some custom pulleys for our shooter this year, and were testing them out of PLA printed on a prusa. During testing, we “thermally reconfigured” our pulley when the shooter was under load. Now we always print the pulleys out of Onyx/PLA-CF.

During inspection at our first event, the inspector found that during the rising and falling of the arm, it could clip out of the 12 inch extension limit. We resolved this by borrowing a sawzall from 4734 and cutting an inch off the end of the arms and then rebolting the intake one hole lower on the 2x1 tubing.
Then at our second event, the inspector said our breaker was in a hard to reach area and had to put it on the outside of the robot. There was a lot of redrilling and rewiring involved in fixing that one.
