Adapter to attach a M249 nutsack to your AR-15. It is meant for use with a belt-fed upper, but larping with a nutsack on a regular AR is pretty fun too. These can cost quite a bit for the aluminum version, but even the polymer ones are fairly expensive for what you're getting. Now you don't have to throw your money away.
The adapter can be pretty tight for regular M249 nutsacks with a metal latch, but they will wear in. A little sanding can help with fitting. AC-Unity nutsacks with their plastic-only latch should slide on no problem. If people want a slightly looser adapter for the metal latch nutsacks I can be convinced to release one.
Print settings: See the included picture for print orientation. Print it with your preferred settings but if you aren't going with 100% infill, then I recommend using at least 8 walls or an infill modifier overlapping the area the nutsack slides into set to 100% infill. Supports are useful for the one major overhang.
