Update 10-23-2022:  Now there are files for a version of the box that can be printed with the Prusa Mini!

Print 1 lid and 1 box, and snap them together at the hinge. I printed mine at 0.32mm layer height with a 0.4mm nozzle. it took about 15 hours for both pieces (if I remember correctly)

Stores up to 60 AA, 24 AAA, 5 C, and 8 9V batteries

(Small box stores 50 AA, and the same amount of AAA, C, and 9V batteries)
