Ring hole measure tool

A ring sizer for measuring rings, o-rings, holes, etc. You can also measure outer diameters of fingers or other things. It measures from 11mm to 25mm in diameter with 0.5mm steps. My printer is not that good at printing small characters, so I made little label that can be printed on a regular printer and glued on the side of the tool. That not the standard for ring sizes, which can be found here https://en.wikipedia.org/wiki/Ring_size, but I wanted to make it more universal. Also I recommend to find yourself keychain metal wire to organize the bits.
