It's a 10mm rod tolerance test 1x1 grid for Zack Freedman's Gridfinity system.

Should give an idea on how tight to offset your parts that fit together, and doesn't take up a lot of room.

On my bambu I was able to get the rod even in the .06 offset, so maybe I need to make a version with lower fits maybe .02-.07 offsets.

Can print multi color like I did or print the one without the filled in text.
