The plate is 1 mm thick, which is a bit more than the sheet that comes with the computer, but it fits nicely.
I printed mine at 0.2 mm and used some black PLA
Unlike the original i haven't added any adhesive to hold the plate as its hold in place by the lid it self fine.
Note: In the image, I have rotated Shodans face 90 degrees because thats how my UM780 is mounted to the wall by the mount I've made. The Shodan stl file in here is not rotated like so, but on “normal” orientation
