This all started with a thread from Reddit, where someone had tried to identify a trackball that an editor was seen using in a screenshot. Turned out to be an ordinary Logitech m570 on a wedge. After some discussion, someone suggested it could easily be 3D printed, so I took that as an opportunity to teach myself how to design and 3D print objects.
The latest design, the MkⅦ, is the one I am currently considering the "final" version. At 25% Cubic Infill it is quite stiff and very stable, but needs some kind of grippy surface to be applied to the feet. 0.5" rubber feet should be easily sourced. Given the strength and stability of the design, you may be able to get away with only 10% infill, and use a different pattern.
The other versions are included to establish a continuity of my design history, as I learned it, and are provided in case anyone is interested in playing around with those designs.
