Files
Case
Case files and drawings are in the case folder.
The files are designed for CNC machining and include the drawings for ttap callouts and such. For 3D printing, you may need to modify the files.
Plate
Plate files are in the plate folder.
A DXF file is included for machining/laser cutting.
KiCAD files for an FR4 plate are in the plate/sifrl-plate folder. Gerber files are in the plate/sifrl-plate/JLCPCB/gerbers folder.
Either way, order 1mm thick plates.
PCB
Main PCB files are in the pcb folder.
Gerber files are in the pcb/JLCPCB/gerbers folder. Assembly files are in pcb/JLCPCB/assembly folder.
A 1.6mm thick PCB should be fine. 1.2mm could work.
Firmware
The keyboard uses QMK/VIAL. Firmware file for it is in the firmware folder.
QMK source files for the board are in this repo.
Daughterboard
The board uses my own version of the squatterboard. See the repo for more details.

Questions
How big is the Sifrl main pcb PCB?
It measures 346.1 × 93.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sifrl main pcb use?
177 parts, built around the RP2040, W25Q128JVSIQ, SRV05-4 and XC6206P332MR. 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 Sifrl main pcb KiCad files?
From the ramonimbao/SpaceInvadersFRL repository on GitHub, at the commit this page was made from: the board is pcb/sifrl-main-pcb.kicad_pcb and its schematic pcb/Matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sifrl main pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask ramonimbao before reusing the design.
