KamSnaps Press Centering Guide

I've been making biothane and leather gear on a KamSnaps DK-93 Handpress for a while, but getting evenly spaced holes and well centered holes for the rivets was always kind of a nightmare for me. So I made a centering guide!

They slide over the anvil and provide a centering guide for the two widths of Biothane that I work with, which are 5/8in and 1in. I might add more widths in the future, but I'd prefer to wait until I have the material on hand so I can test it. You're welcome to remix/modify as seen fit to make it match your needs - Just please don't reupload it as-is.

I made this specifically to fit the anvils for the Kamsnaps DK-93 presses, but there's a number of mimicry "Green Machine" presses on the market that it might fit as well. As long as it's roughly 27-28mm diameter and has an interchangeable brass plate (for easy disassembly), it should work.

I printed these on my unmodified Ender 3 Pro with the lowest of Cura's default presets (0.28mm) and while they might not be pretty, they work just fine. Please note that these have very tight tolerances for the actual anvil so they don't wiggle, but they won't go on or come off very easily. I usually flip the anvil over and press it into place with the handpress itself, and then take it off by pressing on the brass plate until it disassembles.
