Arrgh! I hate it when finished rounds start bouncing out of the little red AkroBin and hitting the floor! Happens around what, 80x 9mm, 70x 40SW, 60x 45ACP, and less than 50x 223/5.56, no? Irritating! This quick-to-print little gizmo slips right into the front "label holder" and stops the fancy brass/copper/lead from bouncing off the concrete floor from now on!
It's thin and has gaps on either side as a compromise for very easy printing with minimal supports (see printing notes). A couple of external struts keep the plate plenty stiff in actual use. The photo with reloads in it shows 160 rounds of .40SW sitting comfortably.
