Following the naming convention (MikeTypeson, Clacky Chan), Stephan (Rollercole) Møller shared Leonardo KeycapRio – a tented unibody MX keyboard. The custom PCB uses squiggles to allow bending without breaking it.

Just finished my latest board, the Leonardo KeycapRio. He is the slickest looking board I have made so far – Stephan.

Features

• 30 keys, 5x3+1-ish monoblock split
• MX switches, hotswap
• single flexible PCB
• RP2040 Pro Micro controller
• 3D printed tented base
• ZigMkay firmware

No screws, no glue – the PCB is press-fit onto the tenting base.
