Pmag Style Dust Cover

Printable version of a dust cover for Magpul AR-15 Pmags

Included a .step file if anyone wants to improve it!

I print with it on its side, 100% infill, concentric walls and infill. I use .2 layer height but I think most any will work. Also use tree supports in Cura.

EDIT: I've had a few failures along layer lines since the part is under tension when installed on the mag. It wastes a lot of filament for the supports, but I've found if you print on a 45° angle with the bottom of the cover facing down, it results in a stronger print. I haven't had any layer line failures with this method yet.
