The prompt
Create ONLY the TOP VIEW and HALF-SECTION FRONT VIEW of the pulley. Use mm and follow the reference exactly. Preserve Ø130, Ø80, Ø64, Ø20, 40 mm thickness, 5/20/15/15 mm steps, and the shown 60° and 45° angles. Keep all features concentric and proportional. Half-section: left half normal, right half 45° hatched; do not hatch holes. No invented geometry, extra holes, spokes, or perspective. Clean black engineering lines, portrait layout.
