Primers for Dummy Cartridges (SCAD)
thingiverse
The title says it all. The OpenSCAD file can be adjusted as needed, and has presets for SP/SR, LP, and LR primers, as well as the table listing the standard dimensions from the SAAMI spec. The SCAD script will automatically generate a grid of however many parts you want. Three STL files are included using the presets which I used, though you may need to adjust things to get a good fit with your material and printer. I printed these in SUNLU/JAYO Silk TPU, though there are probably more durable materials than that. I used 100% infill, 0.2mm layer height, no rafts or brims. Printed at 235C on blue tape on an unheated bed.
