## What it is
Charybdis is an open-source ergonomic split keyboard design with an integrated trackball, intended as a full mouse replacement. The repository provides 3D-printable case files (STL/3MF) in 4x6, 3x6 Mini, and 3x5 Nano variants, along with build documentation and compatibility with other BastardKB keyboards.

## Use cases
- build an ergonomic keyboard with a trackball
- print 3D case files for a Charybdis keyboard
- replace a mouse with a keyboard-integrated trackball
- build a split ergonomic keyboard at home
- find STL files for BastardKB keyboard cases
- pair a Charybdis with a Scylla or Skeletyl half

## When to choose
- you want a DIY ergonomic keyboard with an integrated trackball
- you have access to a 3D printer and want open-source keyboard hardware
- you want a mouse-replacement solution built into your keyboard

## When to avoid
- you want a ready-made, off-the-shelf keyboard
- you need software only and no hardware assembly
- you are not comfortable sourcing components and soldering
