Shotgun Shell Power Bank Case

I saw something in Cabela's and thought "I'll 3D print a new shotgun shell case for my power bank I bought for $10" and that's how this design came about.

I am currently working on a version with a screw on bottom piece instead of a cap that snaps in.

I recommend printing in ABS because the charger may get hot enough to distort PLA. If you have red and gold filament this would be great to do a filament swap halfway through the print. Also the low refinement one should produce some lines
