Tactile Switch Sizer

I bought some [6×6×9mm tactile switches](https://www.amazon.com/gp/product/B06VY1WJ8Z/) and needed to figure out the size of hole that would comfortable fit the caps.

Hole diameters range from 6.2 mm to 7.3 mm in increments of 0.1 mm.

For these particular switch caps, 6.3 mm is the hole size I would recommend.
