The prompt
Create PART 2: SLIDING PISTON AND CONNECTING STEM for the mechanical snap-action overpressure warning mechanism. This component must fit inside PART 1: PRESSURE_SENSING_CHAMBER. Use the following preliminary dimensions: - Piston head diameter: 35 mm - Piston head thickness: 7 mm - Central stem diameter: 10 mm - Stem length: 42 mm - Include a suitable sealing groove around the piston head. Design requirements: 1. The piston must slide vertically inside a 36 mm chamber bore. 2. Maintain suitable clearance for smooth movement. 3. The piston must respond to hydraulic pressure acting beneath its head. 4. The central stem must extend outside the chamber and transfer movement to the snap-action linkage. 5. The piston must remain properly guided and aligned. 6. Avoid unnecessary side movement or tilting. 7. Include a practical mechanical connection point at the end of the stem for the connecting rod. Generate one editable parametric solid CAD part. Use millimetres. Name it SLIDING_PISTON_AND_STEM. Do not create the chamber, spring or linkage. This part must be compatible with the dimensions specified for PART 1.
