Vise mount for the RCBS Automatic Priming Tool. I didn't want to mount it permanently to my bench. This mounts in a vise, and hangs on the wall when not in use. It also has provision for 2 Akro bins. The section that mounts in the vise needs to be at least 50% infill for strength. Mine was printed in PLA.

V4 has the primer tube and priming pin storage locations built in. I found that to be a bit of a hassle when removing the priming tube being used when it still has primers in it, because I had to remove everything from the storage holes to prevent them ending up on the floor. So V5 eliminates those, and I've made a separate storage solution for the extras, here: https://www.thingiverse.com/thing:6108132
