Awesome! I've replaced my desktop monitor with e-ink, and use an e-ink tablet for reading and browsing. My laptop is the final LED screen in my life. I don't know if I have the skills/time to DIY this but it looks promising. Great work!
You only need a small 3d printer for that project, 256 mm square bed, as all the big pieces are sliced in two. And it is not too difficult to assemble the piece from Framework 13. It is all "screw in place".
