This is a WORK IN PROGRESS.

This is a remix of the original CAD mouse / Spacemouse using Hall Effect Sensors. In the original the point of rotation is offset very low under the knob. My idea was to bring the whole suspension up, closer to the center of the control knob (or bring the knob lower closer to center of rotation, depending how you look at it). This should improve the handling and reduce the unintentional roll inputs when trying to do translate inputs.

When using this spring you need to use the modified knob and probably also the smaller case. Use two M4 nuts and two standard washers to install the new spring. Add threaded inserts like in the original magnet plate and after adding magnets screw on the knob.

I uploaded 3 different thicknesses of the spokes. Start with 0.5mm and try the thicker one if your TPU is too soft.
