CAD Machine Design for S-Shape Fabric Movement

I need a CAD design of a machine that can be almost 3D printed. The machine should rotate fabric in a continuous S-shape two times. The fabric should be snapped to the track of the machine with magnets, allowing for easy attachment and detachment.

Key requirements:
- Continuous S-shape movement is crucial
- Easy attachment/detachment via magnetic snap
- Precise rotation control

Ideal skills and experience:
- Proficiency in SolidWorks
- Experience in designing 3D printable machines
- Strong understanding of mechanical movement and fabric handling
