Build it with your AI

Using the CheapCADTools connector, design a 5 : 1 planetary gear set in Planetary Gear Designer: module 2 mm, 20° pressure angle, spur teeth, an 18-tooth sun, 27-tooth planets and a 72-tooth ring, three planets, a profile shift of 0.2 on the planets, face width 20 mm. The sun: a 12 mm bore with a keyway 4 mm wide and 1.8 mm deep. The carrier: each planet on a 6000 ball bearing. The carrier's output: a 16 mm bore with a keyway 5 mm wide and 2.3 mm deep. The ring: eight M5 bolt holes, a 14 mm rim below the roots. Set parts in mild steel and the Strength check's sun, planet and ring material to steel, through hardened, grade 1. Check the design, apply any Auto-fix it suggests, then export every part (the sun, a planet, the ring and the carrier) as STEP and STL and give me the download link.

Paste it into Claude, ChatGPT or any AI app with the CheapCADTools connector, and it designs this planetary set with you, checks it and hands you the files. How to connect your AI.
