Nutchecker - M3 - M4 - M5 - M6 (tolerance test)

This thing i whipped up in Fusion 360 while designing something for a table saw.

I was getting inconsistent fits for the nut and bolt i was using and got tired of only printing for the garbage can.

I designed this little nut checker to see whether a metric hex-nut or bolt would fit and made the radius bigger each step with 0.05mm.
