This repository uses OpenSCAD to make 3D-printable keyboard cases. Initially this was simple modifications to an existing case for the Redox handwire keyboard, but now also provides the possibility to make a new case generated in OpenSCAD from scratch.

When cloning, you need to make sure you get the submodules, e.g.:

git clone --recurse-submodules https://github.com/Lenbok/scad-keyboard-cases.git

Have a look in redox-rev0-mod for my modification of the original handwire Redox case.

I then wanted to design a new case for the Redox that was inspired both by the Redox Rev1 case and the Iris, and I thought it would be nice to start with the layout from the Keyboard Layout Editor JSON file (in this way it could be extended to other keyboards). Existing tools I had found for going from KLE JSON to OpenSCAD didn't work for split keyboards where some keys are rotated, so an updated tool is provided here that seems to work on the split keyboards I have tried.

Examples: Redox and Corne keyboards.

If you have another KLE JSON file you want to convert, run the included jsonPositions.py which spits out the key layout to a minimal OpenSCAD data structure along with some data access functions. E.g:

python3 jsonPositions.py -v redox_layout <redox-rev0b/redox-layout.json >redox-rev0b/redox-layout.scad

Where -v redox_layout designates the OpenSCAD variable name used to contain the layout data in the generated file. Then make a top level OpenSCAD that includes this along with keyboard_case.scad, e.g.:

include <redox-rev0b/redox-layout.scad>
include <keyboard_case.scad>

Then to make a case, you mostly just need to define a polygon describing the outer boundary of your desired case, a set of points for where to put case screw holes, and optional positions for tenting supports, and call the top_case and/or bottom_case modules.

See some of the cases here for examples:

Redox:

CRKBD (main shell is top half):

CRKBD "alternate" (hi-profile, main shell is lower half):

CRKBD "minimal" (here using bottom mount mcu and reset for low profile):
