To celebrate getting new batteries for both of my digital calipers, I made a quick and easy wall or desk mount for a MK802ii, which I’m using Debian and motion to stream the webcams on my 3D printers (1 each and 1 for the room = 3). The HDMI cover was made by inverting an already existing HDMI plug in Sketchup online library. Although I haven’t used it for very long, I figured having the MK802ii vents (2x sets of air holes) facing out would be the best way to dissipate heat. If heat is still an issue I’d add a bracket for a 5v 40mm fan, and use part of the 5v USB.
Here’s the STL file: mk802_ii
