If you have more than 19 AAAs, which is what Fredslund's design accommodates, you can print a second box, or you can print a layer, which hekps keep your battery collection in one place!

All pieces print without supports, as long as your printer can bridge reasonably well.

I printed in PLA with 0.4 nozzle at 0.2 layer height, but it can probably be done faster.

I suspect, but I haven't checked yet, that Fredslund's other boxes (AA Storage, and SD Card Storage, etc) will be compatible with this tower. If they are, then we could potentially create a tower of AA and AAA batteries.
