Tiny model to test clearance or interference fits

There are 16 possible combinations from -0.2mm (interference) to 0.55mm (clearance) in 0.05mm steps.

Just print, find the fit that works for you, and add the two numbers together to get the total clearance (in um)

The model is only a few grams and takes <10 mins to print both blocks

EG on my test 0 & 0 (no clearance) could be assembled via press fit and not removed

0 & 200 (0.2mm) is tight but easily removable and can rotate

100 & 200 (0.3mm) begins to become loose
