Brass Annealing Shell Holder

Printed shell holder for mounting onto drill chucks to anneal brass with a torch. For those that don't want to build/buy an annealing machine, yet one step above chucking up a socket

Simple press fit for inserting/removing cases, if shell holder loosens up after lots of use, just print a new one.

Currently for cases based on 308 Winchester and 6.5 Creedmoor.
