12G shotshell crimp reducer

Here is my super basic kit for reducing the crimp of a fired 12gauge shotgun shell. Good for re-crimping or before cutting to make it easier.

1. Print parts
2. Insert fire shotgunshell into the shotgunbottom.stl (might need to resize the shell to fit)
3. Insert ShotCrimpRemover.stl with the rounded end into the case mouth and push it/ mallet it in.
4. Remove ShotCrimpRemover.stl
5. The shotshell crimped mouth will be much more open, easy to reload and re-crimp or cut off.
