CAD
I designed it using autodesk fusion
Everything fits together with 5 m3 screws and bolts
Firmware
I wrote the firmware using qmk.
Notes
If you want to change the mapped you can use via with the included via.json file which you can find in the firmware folder https://usevia.app/
Making this pad was fun, I got to learn qmk fusion and kicad which I can use fluently now, fusion and qmk not so much.
I have used https://github.com/hackclub/hackpad/blob/main/hackpads/cyaopad/README.md as a template for my readme
I have used https://github.com/dancarroll/qmk-bongo for the bongo animations I have also used ai for explaining what does what in qmk, afterwards I have written the code myself and ai has helped me debug it.

Questions
How big is the Pad pcb I guess PCB?
It measures 143.3 × 57.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pad pcb I guess use?
13 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pad pcb I guess KiCad files?
From the kripusek/krip-pad repository on GitHub, at the commit this page was made from: the board is pad pcb I guess/pad pcb I guess.kicad_pcb and its schematic pad pcb I guess/pad pcb I guess.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pad pcb I guess design in my own project?
Its repository states no licence, so its author keeps all rights: ask kripusek before reusing the design.
