Quickly generate holders for different battery sizes (aaa, aa, c, d, 18650 etc) in custom layouts (1x1, 2x1, 3x3 etc).
Ends have cutouts for adding contacts and are only attached to one side so they should flex a little if not made too thick.
Simple to add new battery types by supplying a name and dimensions.
Easy to print, no supports required.
