Build it with your AI

Using the CheapCAD Tools connector, design a two-gear drive in Gear Designer: module 3 mm, 25° pressure angle, face width 24 mm. Gear 1: 15 teeth, a 15 mm bore with a keyway 5 mm wide and 2.3 mm deep. Gear 2: 45 teeth, a 25 mm bore with a keyway 8 mm wide and 3.3 mm deep, a hub on one face, Hub OD 55 mm, Hub Height 15 mm, 6 hub pins of 5 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.
