To do

What you'll need

A 3D printer. I did mine with a Creality Ender 3.
Black and White filament
A Raspberry Pi, any model up to the latest model 3 B+ will do.
A small MicroSD card, 16 Gb will be more than enough.
A compatible USB gamepad and a wireless mini keyboard are strongly recommended, but not a requisite.
A micro USB power supply with a little more juice than the standard Raspberry Pi one, because we'll be driving a screen too. 3 Amps will be enough, like this one.
The Waveshare 2,8 inch. screen for Raspberry Pi, the exact model is important here.
26-lane IDC ribbon cable with connector to connect the screen to the Raspberry Pi.
A male IDC 26 pin socket like this to make it easier to plug and unplug the display.
A panel mount switch button that fits the 15x10 mm. rectangular hole in the Base, this one fits perfectly.
A micro USB cable extender with panel mount. The Base is prepared for one with a 28mm. distance between the mounting screw holes, this one fits perfectly.
Two tiny round 10 x 2mm magnets for that satisfying clicky sound when it closes.
The usual simple soldering stuff, glue and some patience.
