The prompt
Design a small 3D-printable experimental palm-mounted wall-grip prototype. Size: approximately 100 × 115 × 30 mm. Make dimensions adjustable. Include: * Curved ergonomic palm plate with rounded edges. * Replaceable 70 × 55 mm gecko-inspired dry adhesive pad on the wall-facing side. * Removable adhesive cartridge. * Small hinge/pivot allowing the pad to move 2–5 mm between CONTACT and RELEASE positions. * Mount for a small hobby servo to control the release mechanism. * Mechanical hard stop and manual release. * Recess for an FSR pressure sensor to detect wall contact. * Cable channel for a flex sensor running toward the fingers. * Electronics compartment approximately 55 × 35 × 15 mm for an ESP32. * Four 20–25 mm strap slots. * M3 screw mounting holes. * Rounded edges and PETG/nylon-friendly geometry. Split the design into printable parts: 1. Palm plate 2. Adhesive cartridge 3. Hinge/release mechanism 4. Servo bracket 5. Electronics cover 6. Sensor plate 7. Cable clips Use standard M3 hardware and heat-set inserts where useful. Make the adhesive cartridge replaceable so different dry-adhesive materials can be tested. Include an attachment point for a laboratory force gauge so the prototype can be tested against a wall with weights. This is a laboratory prototype only and must NOT be designed or represented as human climbing or fall-protection equipment.
