Pins and Tabs used for registration of multi-color relief prints.
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!
Note: These are very thin prints! I printed mine at 0.1 layer height.
The tabs use about $0.01 worth of plastic, so if you ruin one trying to shave it down to a perfect fit it's no big loss.
The OpenSCAD file is included if you want to make any changes.
