I want to build a box that i can test fire into that will reduce the noise considerably so i can test fire into my garage. Has anyone built something like this. Is it feasible im thinking something i can insert my hand and pistols into that will catch the bullets and not disturb/alert my neighbors. Any ideas of what would be required Im thinking something similar to the “ftn shut your trap” but not something that sits at the end of the barrel something that encompasses the entire gun like a mini soundproof room

Every thing i print in pla+ has been pretty dimensionally accurate on my K1c. However when i print the same thing in pa6-cf. (all fillament sunlu) the dimensions end up slightly smaller and the tolerances are arguably too tight. Magazines dont slide in and out easily, mag catch barely fits and wont slide. Pin holes are too small. Etc.

How would i address this. As it seems filament dependent not printer issue
