Dewalt 18v XRP Battery Holder Wall Mount

I was having a really hard time finding a wall mount battery holder for my father-in-laws Dewalt 18v XRP batteries. I eventually found one on Thingiverse by henryhbk, but it didn't hold securely enough and I was worried about the back plate separating from the bottom plate. So, I remixed it in Tinkercad. 

Printing: This really should be printed in PETG, ABS, or ASA.

Shown printed in PLA (for controlled environment), 5 perimeters, 20% cubic infill, no brim or supports, with a .4 nozzle and .2 layer height. It used 59.24g /20.52m of filament.
