Here are my pins and tabs used for registration of multi-color relief prints. They are heavily inspired by the Ternes Burton system, and I’ve found a similar design on Thingiverse but as usual, these are mine.
Print at least two pins and then as many tabs as you need to do a print run.
When printed the tabs should fit tight into the pins. This is by design. Depending on your printer the tolerance may or may not make a good fit. I print the tabs and then if they are too tight I just give them a very small swipe inside the hole with an X-ACTO blade.
Once shaved down the tab should fit the pins slightly tightly but not too tightly, and not too loosely obviously. Welcome to 3D Printing!

With my latest batch of handmade paper the blue painters tape I use tends to pull up a lot of the paper when removing it, but the typical printmaking paper you can buy (this is some Strathmore paper) holds up just fine.
You can get the STL and .scad files from Printables.com – Printmaking Registration Pins. Note: These are very thin prints! I printed mine at 0.1 layer height. But hey, print them if you need them!
