The prompt
A 3D-printable CAD design of an organic, human-like robotic 'Palm Housing' (Part 1). Output as a single STEP/IGES file with dimensions in millimeters. Specifications: - Material/Aesthetics: Heavy-duty 3D-printable plastic. The outer body must be tapered to look like a human palm: 100mm long (Y-axis), 85mm wide at the front/knuckles (X-axis), tapering smoothly to 55mm wide at the back/wrist, and 35mm thick (Z-axis). Fully round the bottom and side exterior edges (using 10-15mm fillets) for an organic, ergonomic human-like shape, keeping the top and back flat. - Internal Pocket (Slider Track): From the top flat surface (Z+), cut an internal rectangular cavity 70mm long (starting 15mm from the wrist end), 45mm wide (centered along the X-axis), and 25mm deep, with perfectly straight, non-rounded internal walls. - Back Port: On the flat back wrist face (Y=0, Z=15), add a Ø12mm horizontal through-hole that opens directly into the internal sliding track (for an actuator rod). - Front Features (Knuckle Hinge assembly): Along the 85mm front edge (Y=100), create four evenly spaced double-wall 'clevis' knuckle brackets. Each bracket should consist of two 4mm thick vertical tabs with a 10mm gap between them, featuring a horizontal Ø3.4mm through-hole (X-axis) for M3 bolts. Directly below these, cut five vertical slots (10mm wide) through the front wall to allow linkages to pass inside.

You Design a 3D-printable mechanical palm housing block. Output as a single STEP file in millimeters. Specifications: Overall Shape: A solid block 100mm long, 85mm wide at the front, tapering smoothly to 55mm wide at the back, and 35mm thick. Round the exterior side and bottom edges with 10mm fillets for an ergonomic shape. Keep the top face perfectly flat. Internal Track: From the top flat face, cut a rectangular cavity 70mm long, 45mm wide, and 25mm deep. Do not round the inside of this cavity. Back Port: On the narrow 55mm back face, cut a 12mm diameter horizontal hole straight into the internal cavity. Front Hinges: Along the wide 85mm front edge, add four evenly spaced clevis brackets. Each bracket consists of two 4mm thick vertical tabs separated by a 10mm gap, with a 3.4mm horizontal hole passing through them. Directly below each bracket, cut a 10mm wide vertical slot completely through the front wall.
