The prompt
Create two separate mechanical parts for 3D printing. PART 1 - FLYWHEEL: Solid cylinder, outer diameter 200mm, height 80mm, with a centered through-hole of 25.4mm diameter. PART 2 - CRANKSHAFT: Horizontal shaft, length 300mm, diameter 24.7mm. On the shaft at position 190mm from left end, add an eccentric disk: diameter 60mm, height 20mm, with an offset pin. The pin is located 15mm from the disk center axis, pin diameter 24.7mm, pin height 18mm. Both parts need manufacturing clearances for 3D printing. Export as STL.
