2 Cell in-series holder for SR57 button batteries

This is a minimalist battery holder designed to fit 2 SR57 button batteries in series as a very compact 3.0V supply.

The batteries fit easily inside, and are held in snugly with the bare ends of AWG 30 wire placed in the hole on either side. There is a slot in the back so the batteries can be easily pushed out of the holder when needed.

Update 9/9/18: Fine Tuned the dimensions and oriented to optimal print position.
