Calibration Ruler Hole Size Checker

thingiverse

I created this specifically to monitor shrinkage on holes within designs. The ruler should be precisely 3 millimeters in thickness. If you decide to remix or make changes, please upload them back with all original solid works files intact so everyone can use them, and those who don't have Solid Works can also benefit from the modifications. I always include the original creation file along with the STL file, allowing users to play with the design if they choose to do so.
