I added the CAD files and links for a 3D printable enclosure to the GitHub repo. This is a larger project box for use with the breadboard testing variant. The final version for proper PCB will come later but some may wish to have theirs on a breadboard so this will probably be handy in the future
The files are customized from another Thingiverse design you can find in the links/attribution. You can use the website customizer to change the design to suit your design for any changes needed.
