Lee Load Master Primer Tray
Description
I wanted a primer tray that would take CCI primers from the square box without overlapping like with the round tray. I printed red_rider95's primer tray and had trouble with the cover staying tight and the latches breaking. I did not need to use the funnel stop since I use an angled screw driver to stop the primers from falling out when placing the tray in the press so I removed it. I made the funnel the same dimensions as the original round tray so this tray should work for small and large primers. After many variations of latching methods I decided on using a lever type latch to hold the cover on. Since the original round tray has a grid on the bottom for stiffness, I used that method to hold a lever type latch and increase stiffness. The latches on the cover are glued on so they can be printed laying flat for strength. The grid on the bottom is glued on after putting the levers in. Some filing or sanding of parts is needed to get things to fit. The glue I used is CA (cyanoacrylate or Super Glue). I had to print the cover at 1.004 scale for X and Y since my transparent PLA seemed to shrink a little. The latches are setup so that all levers latch towards the funnel / press so gravity will help keep them in place when on the press.
