Build it with your AI

Using the CheapCAD Tools connector, design a two-gear drive in Gear Designer: module 4 mm, herringbone, helix angle 30°, face width 40 mm. Gear 1: 20 teeth, a 25 mm bore with a keyway 8 mm wide and 3.3 mm deep. Gear 2: 60 teeth, a 40 mm bore with a keyway 12 mm wide and 3.3 mm deep, spokes: 5 of them, Hub OD 80 mm, Width 24 mm, Rim Depth 26 mm, Fillets 6 mm at the rim and 10 mm at the hub. 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.
