AA and AAA battery holder. Modern design, very strong, functions well.
Flush wall mount MAGNETIC! or drywall screws.
Screw together, M2 x 6mm black oxide socket head screws 6mm and M2 hex head nuts.
Assembly is a little tedious but parts work and fit together well.
I wanted a great looking battery holder that would magnetically mount on my office storage cabinet. I love it, figured you might too.

Settings I used:

Black: D3D Duramic PLA plus 212/60
Orange: YOUSU Orange PLA 212/60
Layer height .16
Print black parts vertically customize supports under AA and AAA placard areas.
Print orange parts flat on the bed, rotate 45 degrees to fit bed
I used Ender 3 pro 220 x 220 x 250

Assembly:

Assembly:
1. Make sure two dovetail parts will fit together. They are snug, but they should go. DO NOT push them all the way together until you have both boxes assembled. (you may not be able to get them apart)
2. Insert M2 hex nuts into slots, work with the holes associated with one orange part at a time. (a couple of my nuts were lose, some were snug, I had to be gentle to keep them from falling out.
3. Use small hex wrench (the smallest that came with my Ender 3) to align nuts with holes.
4. Place orange plastic piece and thread screws together. Don't get too upset, after a couple you'll be a pro.
5. Complete both "boxes" AA and AAA.
6. Slide the boxes together using dovetail joints.
7. Screw in magnets if you want to hang magnetically.

I used these screws:
Mc Master-Carr 91290A013 (there are other M2 socket screws available) M2 x 6mm black oxide socket head (buy 100)
I used these nuts:
McMaster-Carr 90593A024 M2 x .4mm thread (buy 100)
I used these magnets:

After installing magnets, I put 3 layers of blue tape over them, because I didn't want to scratch cabinet, and the magnet was super powerful.
