Over the years I have usually just taped up a piece of card stock to redirect primers into the holes in the press. I have a hole underneath the press that collects primers into a soda bottle… However, I still occasional got a stray that ended up jumping out onto the bench. Sort of a pain when you’re decapping several thousand spent cases in one go.
Anyhow, I was sitting there tonight and decided to sit down and design a “Primer Shield” for the turret press and 3d print it. Turns out that it works very nicely. So I decided to add it to Thingiverse and share the link. If you need something like this I hope it can help you. And if you decide to 3d print these and sell them on eBay, you have my permission…just do right by the price…
