3D Printed RCBS Ram Primer Slot Block - Printer File (.STL)
After printing this improved primer catcher from over on Thingiverse.com I needed something to block slot for the priming tool. This little part keeps the primers from falling out the wrong side of the ram making sure that they end up in your primer catcher and not on the floor.
I print this with 2mm walls and top/bottom.
I found the best oriention for the print to be upside down from how it is shown in the cover image.
