Li-ion Battery Box - Assorted (18350/18650/21700/14500/10440)

This was my very first CAD design: a simple box to hold my spare lithium batteries plus a spot for a single-bay charger. Holds the following battery sizes:

18650(x4)

18350(x2)

21700(x2)

14500(x2)

10440(x1)

Aside from the charger, this model requires two 3X2mm magnets and two M2x10mm screws (slightly shorter may work too). I also included a box without the charger slot, and an extra lid in case there isn't enough vertical room for protected cells.
