Room space

My bedroom is relatively small compared to how much stuff I keep in there. One wall is covered in wood guns, the closet houses my sister's gaming setup, the other wall has the dresser, TV, and Xbox, and the wall with the window has my futon/bunk bed. I was sitting down on the futon, after moving my headphones to the floor, that realized I could hang stuff from the bars that hold the mattress up. The first thing I could easily make is a hook for the aforementioned headphones. I measured the bars, drew the hook up in Fusion 360, and 3d printed it. This ordeal took about an hour, not counting print time. And it works!
