Disclaimers
Read Romper's fullsize guide before reading the instructions here. DO NOT LASERCUT WITH THE ITO TEMPLATE AS IS. I'm not sure if the traces are wide enough. It's only good to be used for hand tracing/cut. DO NOT MAKE THE CART IN MY DESIGN. It's not really stable.
I am NOT financially responsible for any mishaps you might have. This is only a guide. Double check all measurements.

Questions
How big is the Rabbit mai rgb PCB?
It measures 60 × 10 mm and has 2 copper layers, 1 mm thick.
What parts does the Rabbit mai rgb use?
6 parts, built around the WS2812B. 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 Rabbit mai rgb KiCad files?
From the Syndric/maimai-controller-fullsize repository on GitHub, at the commit this page was made from: the board is pcb/rabbit_mai_rgb/rabbit_mai_rgb.kicad_pcb and its schematic pcb/rabbit_mai_rgb/rabbit_mai_rgb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rabbit mai rgb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Syndric before reusing the design.
