I have a Mac Mini as my workshop computer and use it with an old Fujitsu screen. Until Continuity Camera was available I had to use my iPhone whenever anyone FaceTimed me and now I can use my Mac AND my iPhone.

Fits on an old fat framed Fujitsu screen, ca. 30,8 mm thick.

Print with a brim/raft unless you are feeling the benevolence of the adhesion deities.
