The prompt
Generate a modular, articulated, 3D-printable lower-limb exoskeleton inspired by the two reference images. Include only the waist attachment, legs, knee joints, ankles, and feet. **All components must be separate, editable CAD parts**, not one fused model, so I can 3D-print, assemble, disassemble, and replace individual pieces. Requirements: - **Legs:** Separate thigh and shin sections with adjustable lengths using telescoping rails and locking pin holes. - **Knees:** Functional hinged joints with removable pins and motion limits. - **Shock mounts:** Mounting brackets on BOTH sides of each knee for two separate gas struts/shocks per leg. Include pivoting connections and adjustable mounting positions. - **Feet:** Separate, detachable foot plates with articulated ankle joints and removable fasteners. - **Waist:** A rigid, printable hip/waist attachment with flat, rounded flanges and sewing holes or slots so it can attach to a separate flexible fabric belt/girdle. Do not generate the fabric itself. - **3D printing:** Design individual parts for FDM printing, with appropriate clearances, reinforced joints, minimal supports, and standard bolts, nuts, and metal pins where needed. Generate an assembled model, an exploded view, individual printable STL files, editable CAD files, and a labeled bill of materials if supported. Prioritize real mechanical functionality, adjustability, modular connections, and printability over appearance. Ensure the joints articulate without collisions and the struts have sufficient clearance and stroke. Use editable parameters for unknown dimensions rather than inventing fixed measurements. This is an experimental prototype, not a validated human-support device.
