Using the CheapCAD Tools connector, design a two-gear drive in Gear Designer: diametral pitch 10, 14.5° pressure angle, face width 25.4 mm. Gear 1: 20 teeth, profile shift x = 0.45, a 15.875 mm bore with a keyway 4.7625 mm wide and 2.38 mm deep, a hub on one face, Hub OD 38 mm, Hub Height 19 mm, 1 1/4-20 set screw in a tapped hole. Gear 2: 40 teeth, a 19.05 mm bore with a keyway 4.7625 mm wide and 2.38 mm deep, a hub on one face, Hub OD 44 mm, Hub Height 19 mm, 1 1/4-20 set screw in a tapped hole. Check the design, apply any Auto-fix it suggests, then export both gears as STL and give me the download link.
