I have been a "repair mentor" at our "repair studio" for 3+ years. It's very rewarding. We did have to set some ground rules: (clean your fan/vac, bring batteries, etc).
Collaborated with our local library.
Anecdote: I gave an apprentice a small vacuum to fix, when he opened it up several live bed bugs emerged. That was fun! /s
