This repository hosts the design files and firmware for a revolutionary 3D printed keyboard, combining the ergonomic brilliance of the HHKB with the finger-friendly ortholinear layout of the Planck. Crafted entirely through 3D printing, this keyboard boasts a unique blend of form and function, integrating a Nordic nrf52840 chip and running on Zephyr RTOS with ZMK firmware.

• Ortholinear Bliss: Every key is strategically placed for optimal finger comfort and minimal movement.
• HHKB-inspired Thumb Keys: Borrowing from the HHKB's design philosophy, the thumb keys offer unparalleled accessibility.
• Fully 3D Printed: The entire keyboard, from the plastic plate and switch plate to the case and feet, is crafted using 3D printing technology.
• Software Customization: Zephyr RTOS and ZMK firmware provide a powerful platform for programming and customization.

• Nordic nrf52840 chip
• Fully 3D printed components: plastic plate, switch plate, case, and feet
• Cherry MX Switches and keycaps for a fully customized typing experience

Leveraging the robust Zephyr RTOS allows for efficient multitasking, optimal resource utilization, and a stable foundation for firmware development.
