Shotgun Shell Coin Holder & Carrying Case

Start with the PDF that I included, it has elevations of the can and shell.

These are large hollow shotgun shell forms that you can store up to 50 US quarters in.  The tops (shell crimp) is threaded.  There is also an ammo can that will hold 10 of the shells.  I've posted two versions of the shotgun shell, one with threads and another with holes for 2mm diameter/1mm thick magnets.  The threaded version works great but needs to be printed at .1 mm resolution.  I tried at .2 fast printing but the threads didn't print well.

You will need to get some 3mm steel rod for the hinges and will probably need to reem out the holes with an 1/8" drill bit.
