I was always looking for my controller and I don't know why nobody came up with this design, altough this is the best place to store your controllers.
This prints perfectly without any supports if your printer is able to bridge the hole for the micro USB.
The holder doesn'T block much of the air ventilation, so you shouldn't get any problems during gaming, with the holder on it. Furthermore, as it lays only on top of the console you can easily remove it. This design is able to hold up to 2 controllers at once.
