This case was designed for .223 ammo but also fits 5.56 Nato rounds. The lid locks in place and the case has “.223 Pedro Pills” on the front. I suggest having your temps properly set up and printing on a brim to help with warping.
Update, new file without the “Pedro Pills” writing if desired.
P.S.: Print with higher infill to help keep the walls of the top portion straight and functioning properly.
