More paintball repairs

This time I was reverse engineering a feedneck for a Smart Parts SP8 marker. These markers are notorious for cracking the body around the feedneck mount, as well as the feedneck itself. This is partially due to the poor force path provided by the original designers, who tilted the feedneck off-center without adding additional support. The customer initially requested an all-metal feedneck, however because of the complex geometry that was a very expensive option. We ultimately settled on two designs, one entirely 3D printed, and the other partially 3D printed with a metal extension epoxied in. These fit up great into the marker, and were a really good example of how powerful 3D printing can be for hard to produce geometries.
