As I mentioned in my build thread ( Here ), I noticed that the buttons on the Boxy Pixel have a tendency to bind up with the shell. Meaning that when you're playing a game like Mario where you're pressing two buttons at once by rolling your thumb, your inputs might not register because the button(s) gets stuck.
What's happening here is that the button will tilt slightly as you're pressing it and the bottom edge of the button will make contact with the sidewall inside the button well. The bottom edge of the button is somewhat sharp and it digs into the wall instead of sliding past it as it should.
So, the solution is pretty straight forward: remove that sharp edge on the buttons. I basically took a small needle file to the bottom edges of all the buttons to give them a nice curved edge. I then followed up with some 500 grit sandpaper cut to about 1/8" wide wrapped over the file to smooth them even further. I finished with a buffing pad just to get them as smooth as possible to promote smooth sliding.
All the buttons are now super smooth and I couldn't get them to bind up even if I wanted to... Update: They actually still bind up, but are better. Still feels gritty sometimes. It's a shame I had to even do this, as this would be easily fixed by just slightly changing the shape of the buttons during production.
