The prompt
Create a compact mechanical two-finger parallel gripper body for a small educational pneumatic robot arm. IMPORTANT: This is STEP 1 of a multi-step design. Create ONLY the main gripper body. Do not create the fingers, linkage arms, or pneumatic cylinder yet. Design requirements: 1. The gripper body must be suitable for FDM 3D printing. 2. The body should be compact and mechanically strong. 3. Create two symmetric pivot mounting points for the left and right gripper fingers. 4. The two pivot axes must be parallel. 5. Place the left and right finger pivot points symmetrically around the centerline. 6. Create a central rear mounting area for one pneumatic cylinder. 7. The pneumatic cylinder will later push and pull a central linkage. 8. The cylinder mounting area must allow later adjustment. 9. Do NOT guess the exact dimensions of the TCP1B16-60 cylinder. 10. Do not create threads yet. 11. Use simple circular holes for mechanical pins or shafts. 12. Add a flat mounting surface so the gripper can later be attached to the robot arm. 13. Keep the centerline clearly defined. 14. Avoid decorative geometry. 15. Keep all dimensions editable/parametric if possible. Initial design dimensions: - Overall gripper body width: approximately 90 mm - Overall body height: approximately 55 mm - Body thickness: approximately 12 mm - Left/right finger pivot spacing: approximately 60 mm - Pivot hole diameter: 6 mm - Rear cylinder mounting area: approximately 30 mm wide Do not generate the fingers yet. Do not generate the linkage yet. Do not generate the pneumatic cylinder. The result must be a clean mechanical gripper body suitable for later assembly.
