The prompt

Create the remaining three mechanical parts for a four-bar linkage (parallelogram mechanism) with the following exact specifications: 1. Fixed base link: Center-to-center distance between holes is 100 mm. Shape is a flat pill-shaped bar with two 5 mm through-holes at the ends, and extruded to a thickness of 6 mm. 2. Upper moving link: Center-to-center distance between holes is 80 mm. Shape is a flat pill-shaped bar with two 5 mm through-holes at the ends, and extruded to a thickness of 6 mm. 3. Lower moving link: Center-to-center distance between holes is 80 mm. Shape is a flat pill-shaped bar with two 5 mm through-holes at the ends, and extruded to a thickness of 6 mm. 4. Suction cup carrier link: Center-to-center distance between holes is 100 mm. Shape is a flat pill-shaped bar with two 5 mm through-holes at the ends, and extruded to a thickness of 6 mm.
