The face buttons (what used to be the shape buttons) are 3D printed! They work surprisingly well. I also had 3D printed dpad buttons, but they were wobbly and weren’t all that fun to use.
The main body of the controller is spray-painted (albeit poorly) as well as the triggers and share/options buttons since I couldn’t find a 3D model for the former and the 3D printed versions of the latter didn’t work very well.
That controller looks like it spend 30 years in a chain smokers apartment
I did not do a good job at spray-painting it!
