Build it with your AI

Using the CheapCAD Tools connector, design a rack and pinion in Gear Designer: module 1.5 mm, face width 10 mm. Gear 1: 20 teeth, a 6 mm bore, D-flat 0.5 mm deep, a hub on one face, Hub OD 16 mm, Hub Height 10 mm, 1 M3 set screw with a captured nut. Gear 2: 30 teeth, a rack. 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.
