Summary

Batteries work so hard for us. It's time to give them some fun!

This project is a follow on from my AA Battery Tower design https://www.thingiverse.com/thing:6516882. I wanted to change the mechanical design to use some gears. I settled on using planetary gears and the Fusion 360 "Spur Gear" Add-in, and found this YouTube post to be very helpful https://youtu.be/71dn-eVdSmc.

Just as in my AA design, I wanted this to assemble easily (no glue is required) and operate simply. The tower holds approx. 30 AAA batteries and will dispense one at a time by rotating the knob. If the batteries are dispensed and not removed, the barrel continues to turn freely and can be loaded up.

I printed the side panel in a transparent material for no other reason than to have the satisfaction of seeing the batteries flow and the gears turn!
