40mm Bofors Projectile
They come pre painted/sanded to fit. Let me know if you dont want a pre painted/sanded projectile, i have extra that came freshly off the printer.
Made of PLA at a 20% infil, 4 top/bottom layers, and 3 wall layers for strength. There is a screw at the bottom if you want to fill it to mimic weight. Makers' mark and description are printed into the bottom of the base.
