Caliper holder designed for peg board from Mars Svratka

This is my first print share, so I'm new to 3D print. I wanted to print some useful holders for my pegboard from the Czech company Mars Svratka https://mars-svratka.cz/produkt/nastenny-panel-30

I was searching for the Internet, but almost all holders for pegboards are designed for the small holes and not for the bigger ones in the shape of a keyhole (or how to describe it).

So I have decided to use some existing models and do a variant for such mount. It is the result of several “proof of concept” :) tries and this one finally pass smoothly. 

My first holder is for caliper, so I hope you will find it useful.
