This is not actually a remix, although it was inspired by: https://www.thingiverse.com/thing:533472 - I made it from scratch in Fusion 360. The original test has the writing on the block even though it is the pin that varies in width so that made no sense to me. However, because the pins are small, I notched them instead. 2 notches for 0.2, 3 for 0.3 etc. - I think this gives a much cleaner look. I also gave the pins a bit of a lip/overhang so that the ones that clear don't immediately fall out when you grab it off the printer.

On my Ender 3 Pro I can consistently get clearance down to 0.2 (although sometimes a bit of elephant's foot makes the pin difficult to remove). If you find this test helpful, let me know or post a make.
