3D printed add-ons for RCBS Trimmers using the Lee Precision Rifle Micrometer to make accurate trim lengths. The cases are held in snap in case-holders with no collets or pilots are required.

One case holder of you choice is included. Message me the case type you are trimming.

The RCBS trimmer is not included. The Lee Mic is included for $20 more.

The casting and cylinder on older trimmer labeled just "RCBS" is different than the "CASE TIMMER 2" and the "TrimPro".

The "TRIMMER 2" version also fits the "TrimPro".

Thanks for looking.
