The prompt
Create PART 1: PRESSURE-SENSING CHAMBER for a mechanical snap-action overpressure warning mechanism for aircraft hydraulic tubes. Design a cylindrical mechanical pressure chamber with the following preliminary dimensions: - Outside diameter: 50 mm - Chamber height: 30 mm - Mounting flange diameter: 62 mm - Flange thickness: 5 mm - Internal piston bore diameter: 36 mm - Bore depth: approximately 25–30 mm - Pressure inlet boss diameter: 16 mm - Pressure inlet passage diameter: 8 mm - Four mounting holes: 6.6 mm diameter - Mounting hole pattern: 44 mm square Design requirements: 1. The chamber must accommodate a vertically sliding piston. 2. The pressure inlet must communicate with the pressure chamber beneath the piston. 3. The chamber must have a closed pressure boundary separating hydraulic fluid from the external mechanical linkage. 4. Include a suitable piston sealing arrangement. 5. Include a mounting flange and mounting holes. 6. Ensure the chamber can be mounted on a flat base plate. 7. Keep the piston bore accurately aligned with the chamber axis. Generate one editable parametric solid CAD part. Use millimetres. Name the part PRESSURE_SENSING_CHAMBER. These are preliminary layout dimensions, not verified pressure-rated specifications. Do not add springs, pistons, linkages or other components to this part.
