The PetruziaMini is my first handwired ortholinear mechanical keyboard, fully 3d printed (except switch, cables, screws and controller obviously), inspired in the number of keys and keymap from some 34/36 keys split keyboards (like the ferris/the corne).

The aim of the project was to create a printable keyboard in as few pieces as possible, even on a 220x220 printer plate.
If you follow the pinout order i used soldering the matrix to the promicro you can use the QMK configurator to create your keymaps or you can write your own qmk firmware!
