Battery Container

thingiverse

I needed a way to organize my office battery drawers so I could easily see the number of batteries in each container without any hassle. I had to have access to the head and tail ends of the battery for taking measurements with my multimeter, and because I have a 3-year-old son who's always getting into things, I needed a way to fasten the containers closed so the batteries stay organized in their containers for longer than five minutes. Custom-sized battery holders in the four common sizes - AA, AAA, C, and D - were just what I needed, printed in common battery unit quantities. The ends of the containers have a peg-and-hole system for aligning closures, and they also feature tapered holes to accept optional 6-32 threaded heat inserts that can be put in using a soldering iron. To get started, you'll need to print two containers at a time if you want a closed container, or just one if you're looking for a tray. To allow containers to be stacked without sliding around, you'll also need to print two times the StackingPin file to create tapered pins that fit the outside holes. If you don't have any loose nuts and want to fasten your containers closed to keep your toddler out, you'll need some additional hardware. In my case, I used 6-32 round-head machine screws (1/2" long for AA and AAA, 1" long for C and D) along with 6-32 threaded heat inserts that can be put in using any cheap soldering iron. The heat inserts I used were from McMaster-Carr and are pretty inexpensive.

If your slicer imports the model very small, it's likely importing in metric by default. To get the same scale in inches, you'll need to scale up 25.4 times.
