Thread: 3D Printing

I have printed mags for 22s. Its tricky to get them reliable and the springs can be hard to make, but it is possible. Average magazine takes me about 5 or 6 prototypes to get a design that works.

I have been printing powder funnels that sit on the shoulder of the case and have the correct size to funnel into the neck. I have about 5 or 6 so far and they work really well, you just plop the funnel on top of the case and its steady enough to hold itself in place. I printed mine from ABS and smoothed the funnel section off with acetone then lubed lightly with graphite so you dont get pesky kernels of powder sticking to the funnel.

I have also printed pistol grips of various types and they hold up great. My dog got hold of a failed print and was chewing on it for 3 or 4 days and couldnt break it, and hes a destructive bastard

I have printed tons of rimfire suppressors and they work really well with some good design. A great tip is to buy knurled muzzle thread protectors the right thread for your barrel, print the hole in the back of the suppressor about 0.7mm smaller than the OD of the thread protector and then heat the threat protector up and press into the back of the suppressor. If done properly this gives a super solid lockup and I broke the suppressor before I broke the thread protector to suppressor joint. You just have to make sure the protector goes in concentric and parallel to the baffle holes, or make the holes well oversize.

I have printed rimfire magazine holders that glue to the side of a stock and hold a CZ mag, have also done cheek risers, small parts trays for disassembling firearms, plus a bunch of other random bits.

I mostly use ABS for parts that will see some load and print at 100% infill. I like ABS as you can glue multiple parts together using acetone, you can also sand and then smooth parts with acetone to get a very professional look rather easily. Its also cheap.
