Battery box for 2 18650 and 2 21700 batteries

by LoloAtelier3D

I've modeled it for a friend who has both types of battery, and I'm offering it for download. A bit hard at first to put the lid on while it's taking time. I'd still advise you to use a good magnet. WARNING: IT'S FOR 2 18650 BATTERIES + 2 21700 BATTERIES
