Backscratcher attachment for reduction scale ruler

Idea born at Stone Designs, this is a backscratcher made for scale rulers Nr. 561 98-4

This hand gets attached to the tip on one of those scale rulers and then you get to scratch your back quite easily!
It gets attached and does not fall easily, it passed some tests, but probably it can be improved!
