Classic Army X9 m4 mag adapter

thingiverse

This is an M4 adapter for the X9. It was printed using 50% infill at a .2 layer height on a .4 nozzle. Support density was set to 5%, and only supports touching the base plate are necessary. The X9 mag part fits snugly but sanding should resolve any issues. The M4 mag release employs a cut pen spring, which is superglued into place.
