Boxer Primer Training Aid for Reloading Instructors and other Educators

This is my first TinkerCAD to Print project. I started with a blank slate.
The purpose of this is as a Training Aid for NRA Reloading Instructors and other Educators.
It shows the inner workings of a typical Boxer Primer as used in Reloading your own ammunition. The three componets should be printed in colors that approximate the real thing.
As is, it should print out at about 75mm or 3 inches in diameter.

There will be more uploads soon.
