20mm Projectile (Fits 20mm Brass)
thingiverse
20mm projectile that I came up with. I use them with real brass for plaques. Prints well in PLA and PETG. I print with infill with PLA and 0% infill with 3 walls in PETG. UPDATE: So the original base fit a little TOO snug. When I test fit it on the brass that I had, the neck of the brass was a little more stretched out than most. So I shrunk the base diameter by .2mm and it fits in all brass perfect. It also doesn't need supports anymore either. So, use version 3!
