Wall mount/stand for an Xbox (or similar) controller, and headset.  Holes are sized for #8 wood screws (which I believe should be equivalent to 4mm wood screws if you don't use freedom units).  Intended to be printed on its side, but people have been having success printing on the back as well. Layer orientation will be less optimal if printed on its back, but for the loads it's intended for that shouldn't be a problem.  

Use whatever structural print profile works best on your printer, I did 4 walls, 20% infill, 0.28 layer height.

UPDATE 10/30/22: Added a second variant that should hopefully maybe work better with Dualshock 4 controllers, based on feedback from Madnessx9.  The controller and headset mounting points are a bit further apart, and the lip that holds the bottom of the controller has been extended a bit.  Hole spacing is the same, so it should be a drop-in replacement if you already put one on your wall.  I don't have a Dualshock controller to test fitment, so if you try it out, post a make with photos and I can try to optimize further. Keep using the original for Xbox controllers.  Dualsense controllers may be better with the original as well.
