The file 'Magpul MOE AAA Grip Battery Holder 3D Printer Model' is (stl) file type, size is 213.0KB.
I took brooksben11's excellent AA Battery holder and modified it for AAA batteries. I had no use for AA batteries on my rig but my red dot utilizes AAA, so this seemed like a great adaptation. The holder fits snugly in the Magpul MOE & MOE+ grips. It holds the batteries tight enough that they don't rattle, but loose enough that the batteries come out if you smack the bottom of the grip a few times with the bottom cover off. Please visit this link if you need one to hold AA batteries. https://www.thingiverse.com/thing:4366039
I printed this out of CF-PETG but I would assume standard PLA would more than suffice for this print. I printed at 40% infill but this is a low impact part so I'm sure 20% would be fine
