The prompt
Create a single-piece compound spur gear for 3D printing. Use standard involute spur gears with 20° pressure angle. Both gears must use module 2. The large gear must have 60 teeth and be 10 mm thick. The small gear must have 10 teeth and be 10 mm thick. The two gears must be coaxial and rigidly connected so they rotate as one piece. Between the two gears, add a smooth cylindrical spacer exactly 50 mm long with no teeth. The spacer diameter should be 20 mm. Add a central through-hole of 10 mm diameter through the entire part. Add 2 mm fillets where the spacer joins each gear. Make the model manifold, watertight, and suitable for FDM 3D printing.
