Snap tolerance test

I intended to make this kind of joint in a much bigger object, and didn't wanted to print it first to see if it worked or not, so I've designed this thing to see if worked or not.
I've tested a tolerance of 0,2mm between male and female (0,1mm for each) and it worked like a charm.
When I fitted one piece on another the match was so perfect that it was impossible to remove it afterwards.

Perhaps I'll make a custumizer later to test several different tolerances if there's some interest in this thing.
