RCBS Primer Tube Rack
Progressive presses from RCBS (or other brands) use primer tubes. The large and small variants (primersize large and small) and different tip types (clipon plastic tips/ slits or integrated plastic) make for a messy work bench. Not to mention the clips popping out when strewn about.
I used a Blackwing Pencil Display Rack by dastels on Thingiverse: https://www.thingiverse.com/thing:4549209 as a base model. I enlarged the top holes to accomodate the larger plastic tips. If you have original slit types you can use the base model.
Print in you favorite press coulor, green red or blue. If you want a smooth finish, keep speeds low.
