Needed a mount for my aftermarket switch pro controller. Nothing fit until i realized that this 3rd party controller was close in size to one of my old xbox 360 controllers. Found a mount for that and after a few test prints and tweeks i had a working model.

Fits this style controller and a basic Nintendo Switch https://www.amazon.com/dp/B07TRQH45S?_encoding=UTF8&psc=1&ref_=cm_sw_r_cp_ud_dp_6R1EHYH71614A12RA1TJ&skipTwisterOG=1&newOGT=1
