Yoga Mat Wall Hanger

I needed to get these yoga mats off the floor when they weren't in use, so my sons could have more space to spread all of their sharp, pointy toys around on the floor. Fortunately, I had plenty of wall space above the weight rack, but how does one hang a big rolled-up piece of foam without it looking weird?

I couldn't find anything around the house that I really liked as a hanger. A shelf would be overkill, and I would still need some sort of lip or stopping mechanism to keep the mat from rolling off. Large hooks like you use to hang bicycles in a garage are not really nice to look at, and I didn't have anything else lying around, so I dusted off the ole' 3D printer and drew this up on a whim. All in all, I'm very happy with the result, especially considering it only took about an hour of design work.
