CAD Model
Here is the CAD made in Fusion 360. It should all fit together with 4x M3x5mx4mm heatset inserts and 4x M3x16mm screws.
Why I made the Hackpad
I thought that this project was pretty fun and was actually my first attempt at doing these kind of things (KiCAD, Fusion 360). It's a nice beginner project that is accessible, and I made it into my own with it's own custom properties

Questions
How big is the Hackpad PCB?
It measures 40.5 × 84 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
9 parts, built around the SK6812. 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 Hackpad KiCad files?
From the Geofoods/Sundeck-Hackpad repository on GitHub, at the commit this page was made from: the board is PCB/hackpad.kicad_pcb and its schematic PCB/OPL_Kicad_Library-master/OPL_Kicad_Library-master/Grove Vision AI V2 Library/Grove - Vision AI Module V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask Geofoods before reusing the design.
