This is a beautiful case for a Raspberry Pi 3 7 inch touchscreen (and Pi). Unfortunately, the center section hasn't been updated for a Raspberry Pi 4, however, in my case, I had an existing RPI 3 (and 3.5" touchscreen) that I needed to upgrade to a larger screen to handle OctoScreen/OctoPrint. There were some comments on Thingiverse that it was for the "older" 7" touchscreens while the newer ones were upside down and that does seem to be the case, however, it's easily handled by setting the rotation in config.txt.
