Coin holder tool Keyring

I though it would be funny to evolve a little bit the usual coinholder for the marker with more option like using it like a wrench.

I usually work with those screw in 3d printing so i decide to make some sort a tiny wrench that can be used to hold a coin (made for 1 Euro coin)

This is awesome how (with the good parameters how strong it is and don't break if you use it. Tested and approved by more than 40 people in my family/friends/etc...
