Using the CheapCAD Tools connector, design a two-gear drive in Gear Designer: module 1 mm, ISO 53 basic rack D, face width 10 mm. Gear 1: 40 teeth, DIN 3967 backlash allowance 24e, a 10 mm bore, a hub on one face, Hub OD 24 mm, Hub Height 8 mm, 3 hub pins of 3 mm. Gear 2: 80 teeth, DIN 3967 backlash allowance 24e, a 12 mm bore, a hub on one face, Hub OD 30 mm, Hub Height 8 mm, 4 hub pins of 4 mm. Check the design, apply any Auto-fix it suggests, then export both gears as STL and give me the download link.

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