Holder for AA and AAA batteries - no tipping or tilting

The battery compartment is easy to fill. The Z-shape prevents the batteries from shifting sideways when inserted.
It holds 21 AA and 18 AAA batteries.
The battery compartment is prepared for wall mounting.
It's also prepared for use with an IKEA pinboard. Simply print out the two hooks and screw them to the back of the box. Images and instructions can be found in part #6283079.
