I bought a used 3dconnexion Space Explorer, and while it was nice, it was annoying that the explorer and a mouse weren't combined into a single device to be used by a single hand, freeing up my other hand for keyboard shortcuts. Therefore, I set out to obtain a solution.
Later, I also found that ambidexterous mice with 6+ thumb buttons didn't exist, so I added that to the specification.
For the 3D navigation, 3 joysticks are used. For mouse movement, a Blackberry trackpad for the thumb (seen in https://hackaday.io/project/167075-thumbmouse) is used, after a positive experience with the One GX1 Pro.
Like Tetent [gd0090], the Turntable is wireless and is designed for use with Teti [gd0022].
