M821 81mm Mortar

Introducing the most accurate representation of the m821 mortar I could muster from tracing drawings from publications and looking at reference pictures.

I was extremely pleased at some users who had printed my old mortar files and even painted them to be true to the real thing! So I wanted to create a better / alternative model for any other enthusiasts out there.

For print settings, I would recommend not going higher than 0.2 mm layer height so the threads fit nice. You can get away with a 0.3 mm layer height and a 0.6 nozzle, although some muscle will be needed to screw on the threads. Besides that no supports needed, print all pieces flat side on the print bed. There is some minor bridging on the tailfin, it should not be a problem for most printers.

Thanks for checking out my model!
