This keycap is designed to fit on the right control of the corsair k65 rgb mini.

And to be printed on a multi material printer.

It might fit other keyboards, i dunno.

In printables, right click the object and split to parts and assign colors.

If you want light to come through like in mine, paint the inside of the keycap in the same color as the letters and logo and use a translucend like material.
