CHIPbag is a customizeable case for Next Thing Co's C.H.I.P..
Options in Customizer, or by downloading the attached OpenSCAD file, include:
Standard or Low-Profile design
Openings for headers
Opening for battery connector
Screw mounts added to sides
Bitbeam added to sides or back
Building bricks added to sides or back
I'm making a lot of tweaks yet, but wanted to share.
