This will hold up to 36 loaded moon clips for the most popular calibers. The dowels print at 1/2 inch in diameter and are 5" tall. Fits in 1/2 of a 50 cal ammo can or a plastic MTM can. I used double sided gorilla glue tape to secure it to the bottom of the can. 16 hour print. Long but worth it. Printed on a prusa mini with PLA
