This is an extended collar for the Dillon 550 primer cup to keep spent primers from ending up on the floor. Tested on a 550c press but should work for all 550 series presses. There is enough clearance so the primer chute does not rub on the collar even when pushing the handle forward during the priming operation.

Supports are not needed if printed with the top of the collar on the printing surface.

Printed at layer height of 0.20mm this should press in easily but not fall out.
