This is a small circuit breaker panel for aviation klixon-style circuit breakers, with a small hole on the back for the metal key to prevent the breaker from rotating in the hole. The holes are offset to leave space for labels below each breaker.
This panel can hold 5 breakers but it's simple to to add or remove them in the tinkercad — please share if you do: https://www.tinkercad.com/things/cUbfWuXvLYM-5-klixon-breaker-panel
Notes:
Almost no-one will need this print but sharing for that 1 other person :)
