It's a completely custom build. I designed the case and made keycaps to fit on 6mm button switches. I printed legends on waterslide decal paper and applied them by hand to every single keycap. The firmware is a custom branch of umbynos's sick68 keymap, which was flashed to an Elite-C microcontroller
A few years ago I made a miniature mechanical keyboard. It was my very first hand-wired custom firmware board and I'm still extremely happy with how it turned out.
