Space mouse DIY, No Springs, Fusion360, Magnets

My version of the space mouse, or 3D mouse – a project that took over a month of design, modeling, prototyping, and refining to achieve this result.  
I aimed to make the project as simple as possible and minimized the number of required parts.  
Unlike many builds you find online, this model doesn’t even require springs for operation.  
The 3D model includes 3 different spring types and 3 spacers for magnets, allowing personalized calibration and user-tuning.  
You will find the wiring diagram in the images.
