WHAT IS IT?
A little box for holding your AA batteries. I designed this to carry extra batteries in my backpack, so that I always have spare batteries for my video game controllers, but you might find it useful in other ways!
NO ADDITIONAL HARDWARE NEEDED
(except some batteries to put inside it!)
MY PRINT SETTINGS
This thing can be printed however you like, really. I did 0.2mm layer height, 3 walls, 15% infill.
