Headphone Holder for Vertical Pipe

I needed a specific way to hang my headphones that I couldn't find anywhere.  I took this as an opportunity to try my hand at making my first 3d model.  This headphone holder snaps onto a 16mm or 5/8ths vertical pipe.  It does rotate on the pipe and it can slide up and down.  For my set up, the bottom of it rests on the shelf edge.
