Summary

After a series of tests and failures such as batteries spinning and blocking or missorting.

I have arrived at a properly working model for sorting and storing AA and AAA batteries.

Specifications

This dispenser offers space for 20 AA as well as 20 AAA batteries. 

The sides have a notch that serves as a quantity indication. 

Dimensions: 55mm W 150mm H 115mm D

Assembly

After removing the small supports first put the front hooks in place 

and then bend the right side slightly so that the rear hooks come into place.

Enjoy !
