This is a bullet tray and bullet for the Bang the Dice game. I love the game and thought I'd spiff it up a bit by adding realistic looking bullets and a bullet tray to hold them.
I printed this using my Prusa MK3 with Hatchbox 1.75mm PLA using the .15mm SPEED MK3 setting in Slic3r. I later also printed it using the .20mm SPEED MK3 setting and it also turned out great. There is no need for supports or brim. The bullet tray can hold 25 bullets. (9mm size)
