This is a simple frame to cover the 5.7" Inky Developer Display from Pimoroni and make the four buttons accessible. If you print the buttons in a translucent material they will also light up with the LEDs. I've designed the screw holes to fit M2.3x6 because that's what I had available. I have included the Fusion file so you can adjust them to your liking (the circuit board has M2.5 holes). It's hidden under “download STL”.
The Raspberry Pi is not included in the frame, since I hang it off to the side. There's no back plate since I just hang my board on the wall with some blu-tack, I might design one someday to friction-fit onto the back

hardware needed: 4x M2.3x6 self-tapping screws
