The prompt
Design a complete, functional, parametric 3D CAD model of a **manual effervescent tablet press using a lever mechanism**, based on the uploaded hand sketch. **Tablet specifications:** - Diameter: 22 mm (fixed). - Target mass: 5 g per tablet. - Initial thickness: approximately 9 mm. - Check whether the dimensions and mass are compatible with the actual powder density. If not, retain the 22 mm diameter and adjust the thickness based on calculations. **Mechanical design:** 1. Rigid steel frame with a stable base and reinforced pivot support. 2. Manual lever with a fixed pivot, connecting linkage, and calculated mechanical advantage. 3. Vertically guided upper punch to prevent lateral movement and misalignment. 4. Removable die, lower punch, and manual tablet-ejection mechanism. 5. Return spring, adjustable stroke stop, and secure mounting hardware. 6. Practical dimensions, manufacturable components, and appropriate materials. **Engineering requirements:** - Calculate lever ratio, hand force, ram force, pivot loads, and nominal compression pressure. - Do not invent the required powder compression force; mark unverified parameters clearly. - Define punch-to-die clearance based on engineering tolerances, not arbitrary values. - Check structural strength, deflection, alignment, interference, and operator safety. - Provide a bill of materials and manufacturing notes. **Required outputs:** - Complete editable 3D assembly with separate components. - Exploded view with numbered parts. - Dimensioned front, side, and top engineering drawings. - Sectional view of the punch, die, and lower-punch assembly. - Detailed drawings of critical components. - Export STEP for 3D CAD, DXF for 2D drawings, and native CAD files if supported. The machine must have a realistic force-transmission path, manufacturable geometry, and functional punch movement. Do not generate merely a decorative model. Clearly identify assumptions and any design parameters requiring physical testing before fabrication.
