Tolerance Test for press fit Box

A simple tolerance test for my Arcade Button Box. I want it to be press-fit, and for figuring out how far the walls need to be apart, I constructed this.
The bottom part is always the same, so you just need to print the top part, wich has the tolerance engraved.

Here are the source files, its made with OnShape CAD.

It might be helpful for others, if you post the results of your printer in the comments.

##Update:
After printing 0mm, 0.025mm and 0.05mm on the Prusa MK3 with 0.2mm layer hight, "FAST"-Profile, I came to realise, that the Prusa prints really well. All three testet tolerances fit well. So now I have to update my Button Box and know, that i do not need to work with tolerances, as the MK3 needs none.
