I decided to experiment with 3D printing pegboard mounts. Surprisingly, they were strong enough for tools. I modeled up some reloading die mounts, and they are working reasonably well. The caliber labels aren't standing out like I had hoped, but I may fill the letters with white out or similar.
There are a couple of iterations shown (added the caliber labeling after) but you get the idea.
