Printable guts for Magpul Pmag Gen M2 to convert it into a 30rd 9mm magazine compatible with any 9mm PCC that utilizes an M4 lower. This design mimics the CMMG conversion mags for the Banshee. There are slight changes to make it play well with being 3d printed.

Pictures show side by side comparisons of what all parts combined looks like next to the standard spring and follower/base from out of the PMAG.

I used PLA+ on mine, printed everything in .15(im sure .2 would be fine) and used 100% infill.

The MainCut, I printed this on its side with supports.

Bottom was printed as is upright, with supports for the bottom not touching, while blocking so no supports are in the box area where it latches, the overhangs turning out fine.

Latch I printed the half rounded part down with supports, with the top end with ears touching build plate. I also printed on the other side, it may be better this way with a raft and supports so it will have a cleaner half round where spring and slide will touch.

The Slide was printed upright with a brim(or raft) and supports.

When it comes to the build, all I had to do was cut off two links of the PMAGs already existing spring and put a slight 20-25 degree bend on the one end.

The four pictures with the pencil pointing to key areas to note.

1. showing where to make the bend at the top of the spring to fit the follower compared to where it is located when on the PMAG follower.

2. showing where to make the cut on the bottom of the spring showing side by side of the pmag. While flipped on this side, you should count 15 links down to the half link on the end so almost 16, make the cut on the 14th link in the middle. So you should have 13 links plus the half cut in picture.
