Battery Holder

This is a slight modification of the beautiful gdalya design from here: https://www.thingiverse.com/thing:3990374
I have printed many holder batteries but in all but this one the batteries have warped and stuck. The design by gdalya works perfectly. Nothing gets stuck and the batteries are easy to remove.
(as it turned out later - this is not quite the same)
The modifications are based on the "old" design from gdalya.
- added some removable elements that allow you to print the holder without support at all.
- Added holes for wall mounting
- added reduced model for AAA batteries for 12 batteries
- added an enlarged model for AAA batteries for 28 batteries - in height it matches the holder for AA batteries for 20 batteries
