This model is based on the design of Ikea Skadis Xbox Controller Holder from Norm.
I needed to change the inner radius for a better fit with the GuliKit KingKong 2 Pro Controller. In addition all edges now feature a radius, which prevents scraping the color of your IKEA Skadis.
You need to print 2 hooks that slot into to 2 parallel holes on the IKEA Skadis and hold the controller securely.
The author remixed this model.
