If you have always wanted a split mechanical keyboard you may be interested in a new creation by Thingyiverse user Coumbaya pictured above.
The 69 key mechanical keyboard uses Cherry MX switches and has kindly been published to the Thingyiverse website allowing anyone to download the files and create their very own using a 3D printer.
Thingyiverse user Coumbaya explains more:
So, this is a quite specific keyboard suited to my needs, but maybe you want to build one or modify this one (I’ve included the SolidWorks files). In their current form, the 3d models do work, but the 2 pillars in the center of each side, designed to take a screw in to hold the bottom plates, broke. So if you know enough solidworks, you can try to design a better way to hold the plates.
The two sides are linked by an HDMI cable so it has enough cables to transfer the matrix on the other side. I used a teensy 2.0++. I’ll probably update this with a link to a geekhack thread later. Don’t forget to print with the plate facing downward.
