Power Bank (2x18650)

thingiverse

This is reusing an old power bank module. It has the ability to show current, which is useful in some situations. It's a first attempt at modular power bank design. Just change the supports and the side print, and you can use almost any module. You'll need M3 acrylic nuts and bolts (superglued with bicarbonate on the bottom half). All fits together perfectly except for the button which has very little wiggle room. You'll probably have to adjust it or just leave it out.
