This is my take on a keycap for the avid Linux user. It shows the iconic Tux created by Larry Ewing (lewing@isc.tamu.edu and The GIMP), I used his drawing as a template to create the relief.

There are different versions with a curved or flat top surface and Tux as an embossing or debossing. There is also a two part version if you want to try it as a multicolored print, but you have to try that for yourself as I have no printer capable of that.

Because you, as a Linux user, probably prefer options, customizability and freedom over convenience ;-) I haven't included any presliced gcode but uploaded .step files of the model instead, so that it's easier for you to do your own forks.

To print my models I used the orientation shown on the last screenshot, a 0,25mm nozzle and 0,12mm layer height, no support was needed. The caps got a nice tight fit on my Cherry G80 keyboard, but it may depend on the printer and settings.

Tux likes to be free, therefore in this case there was only one license that made any sense to me. 

Have fun and if any of you got a multicolor printer I would be interested to know if it works.
