We have this EMU Graphic Equaliser here that are missing the knobs on the gain pots, and one of the pots actually has a broken axis, and it has an unusual diameter of 4mm.
So instead of searching for replacement pots that would probably require me to drill a larger hole in the face plate, I thought I'd try to use 3D printing. I made a generic axis adapter that I can someday extend for other axis types.
So I printed the adapters to fit into the knobs I want to use…
Then I wondered if I could just print the missing part for the broken axis, and join them with a bent paperclip…
I had to use a dremel to drill into the remainder of the axis, it's not exactly aligned but it should be good enough…
Then I bent part of the paperclip in a U shape…
I wanted to try heating the paperclip but I thought I'd just "Hit it with a hammer"…
I'll have to test, hopefully I didn't destroy the pot inside…
Model is here. It can adapt from 4mm, 6mm, 6mm with a plane knobs, to a 4mm axis, or to the paperclip repair.
