"Design a 3D printable spur gear for a NEMA23 stepper motor with the following specifications: Gear teeth: module 2, 20° pressure angle, 30 teeth (≈60 mm outer diameter). Hub bore: 6.35 mm diameter (for NEMA23 D-shaft), tolerance +0.2 mm for clearance. Include a set-screw hole (M4) perpendicular to shaft for secure mounting. Hub reinforcement: add fillets (2–3 mm radius) at the hub-to-gear transition for strength. Wire anchor holes: three evenly spaced circular holes (120° apart) on a pitch circle radius of 25 mm. Hole diameter: 1.4 mm (to fit 1.0 mm steel wire, with clearance). Add counterbore recesses on the gear’s outer face: 3 mm diameter × 1.5 mm depth for ferrule seating. Ensure chamfered exits on holes to prevent wire abrasion. Optional capstan feature: add a shallow circular groove (2 mm wide × 1 mm deep) near the gear rim for wrapping tendon wires. Include small flanges (0.8 mm tall) on groove edges to prevent slipping. Parametric design: allow easy adjustment of: Nu
