This is a screw-under-your-table holder for the Gulikit KingKong 2 (Pro) controller.
Should print properly in the given orientation (the part with the screw holes pointing straight upwards) without supports. 2 Perimeters and 10-15% infill is plenty, PETG might be preferrable for a bit more sturdiness.
You can lead a USB-C cable through the holes in the back in case you use the controller as wired, or to charge it.
The author remixed this model.
Removed the xbox logo and reduced width of the whole thing to match the Gulikit KingKong 2 (Pro) controller.
