Originally, mjongerh wanted a keyboard with some additional keys for shortcuts in games. Then he got inspired by the SpaceCadet, the hyper7 and also jurassic73's Split89, and decided on even more dedicated buttons for shortcuts, macros and code snippets.
Understandably, such a monstrosity wasn't readily available for purchase so the author had to design and build his own keyboard – without prior experience in building keyboards, 3D-modeling or 3D-printing.
Couldn't get the keyboard I wanted. So the only reasonable thing to do was make my own, the Krangle! – mjongerh.
Most parts of the keyboard were printed with a Creality CR-20 and all those buttons are meticulously handwired.
