Storing controllers in a box / drawer / pile in the corner of the room may be easy, but it always worried me that it would damage the controller itself. So, after not finding exactly what I wanted in other models, I decided to make my own. 

Hooks have holes for screws to be mounted to a wall / shelf / whatever. Distance between hooks can be customized as the the hooks are mirror images of eachother, and unattached. I've found that mounted close together hooks outside seems to be wide enough for just about everything, but if you're looking to hang Gamecube Wavebird (or replica type for Switch) controllers specifically, maybe widen the gap a bit. 

Update 2024: I previously only included the left hook, which could be mirrored to create a right hook. Now both are included.
