Given your username, I thought I might contact you concerning your design. A small reloading group of users has been looking for a method of securing pistol/revolver cases into a "thing" to help hold the cases securely while they move through the stages of a prep center such as Lyman. Cases would be inserted into the collet, mouth first up to the web, .020", with the base of the case exposed for conditioning the primer pocket. The length of the case probably doesn't matter in that the thing is hollow. The outside diameter of the case's web, those on the list, varies approximately .2", from .278" to .480". I'm not a designer nor do I have a printer, but I have ordered projects printed from this website. I'm curious if this design would work within the range needed and if not, how much modification would it take to make it work? Any assistance you can provide would be much appreciated; our arthritic hands are limiting our ability to pursue our reloading hobby.

Make a hex and/or square nut (outer shape) so one can clamp it reliably at 60°/90°
