A two-part Keycap for mechanical keyboards with backlight.
First part has the Cherry MX Switch connection (+) and a small hole, so the light is directed.
Second part fits above the first one and is best printed with a semi translucent filament, so it shines through.
Some supports are needed.
The shape is similar to the Keycaps of a Logitech G610 like shown in the pixtures.
I use it a as colorsplash on my ESC Button.
