Modeled for fun some time ago. You can see the textured model here: https://www.artstation.com/artwork/VdGJwP
It have a small circle in the end so it can be used as key chain. I hope you like it guys.
Modeled in Maya and it have some inscriptions with Zbrush.
I printed this horizontally, so i can remove the support of the bar more easy. I think you can also print it vertically.
