A beer keg model with an RFID tag attached.
This was a remixed of a keg model I found on the internet. Very honestly I must say I'm not able to give proper credit because I found the model somewhere, downloaded and simplify the mesh till it was good to print. Then I added the tag on the top of the keg and merge it into a single stl object.
I wrote a post on a blog I started to publish pictures of my prints and potential tips. It can be found here: https://converdbmakes.wordpress.com/
