We are starting to see the world change with the advent of 3-D printing. When one looks around there are a lot of things that can be made with this technology. One of my favorites is the bullet collator which is being made by a number of companies as well as Diyers out there.
I'm going to start a small list in the hope that others might chime in and list what they would be interested in.
1.) Bullet Collators
2.) Magma Bullet feeder assembly with the option of using a air cylinder instead of the spring/lever setup.
3.) Multi tube assemblies for the Star/Magma bullet sizers to use in place of the single somewhat short bullet tube.
4.) Bullet catch assembly for the Star/Magma to catch bullets after they are sized for those using bullet dropper assemblies.
5.) Primer tubes if possible. I don't know if printed technology can do this.
6.) Primer catch trays for single stage ot turret presses.
