Stackable catfood can holder retaining arm

A retaining arm for the stackable catfood can organizer. Prevents cans from falling out the front, if they're too heavy or get too much speed when being loaded up. Arm swings down to hold the cans in place, and up out of the way so you can pull one out. Nominally this needs 2xM3x20 bolts and 2xM3 nuts, but the fit is tight enough you don't actually need these. They just make the action a little more stable. Minor supports encouraged, but it does print well enough without them. Installs in one of the side hexagonal holes in the organizer.I recommend the one in the pictures, although the lower one works well for smaller cans as well.
