From the project

Mantis hex ergo keyboard

Mantis is an ergonomic keyboard designed around hexagonal keys.

This repository contains Ergogen, KiCad and OpenSCAD files for the PCBs, case and key caps, as well as a build guide. You can print a one-page reference and quick start guide of the default keymap.

Mantis is approaching the end of the prototyping phase, currently at version v0.3.3. You can check the git history for older prototype versions.
