Backpack canon

A blastoise inspired canon, to mount on shoulder strap on backpack.Print all in one go, with ams for colour changes.or print separately without ams. i have designed it to be used with magnets of 8mm radius and 5mm tall.if not you can print the shoulder pieces with the “knobs”, tight fit and will hold very well. You can as well print the knobs on the side and glue on for easier installation, i had good successBoost Methis is my first design ever. please boost me to help me grow and make more. on this.
