Description
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!

If you are new in handwiring you can find guides i used here and here! Good luck and have fun!
Some print instructions:
- All pieces are printables in PLA with 0.2 layer height
- Print the Frame.stl upside down, you wont need any support
- In the Case.stl you can just put a custom support on the usbc hole from your slicer, the other parts don't need any
- Consider use brims! They can save your bigger pieces from warping
