Extech 530 Multimeter Selection Dial and Battery Cover

Broke the selector wheel on my older Extech 530 Multimeter.

Extech wants $100 flat rate to fix it (a friggin' plastic part!) and won't sell me just the part.

So I made my own.

Prints fine with supports, put the detent circle facing to the bed. You will spend some time trimming up the wiper mount nubs with a razor knife - just be careful.

If you print this with a 0.2mm nozzle, it'll likely be a lot easier. I did it with a 0.4mm.

I had trouble duplicating the silly detent chain, so
