A CR2032 battery replacement with grooves for contact wires and an opening for getting the wires out. The grooves are sized for the paperclip on my desk which is .72mm diameter, which is also 21 AWG wire.

Wire it up to a 3V source and it should be good to go.

Note that this is untested and will get some revisions.
