This the adaptation of the flat battery storage for around 30 AAA-Batteries.

The design is optimzied for low drawers. The hight of this storage is 51mm, with a length of 220mm.

For the assembly I used M3x6 cheese head screws.

The ramps I would recommend to print with a printing edge.

The top is sliced for the MMU2S
