Nerf Vector Mags

This is a 15 degree angled mag that is designed for short (half length, 35-38mm) darts. Original design work was done by ColinW, I made improvements to feeding and robustness, along with the endcap design. This needs a custom magwell to feed, and does not fit in katana or talon magwells. No supports are needed on any part, but foamblast drum springs are needed for function (like most printed mags).
