17/34 · ANSI 50-2 duplex, ISO 4156 splines

Using the CheapCAD Tools connector, design a two-sprocket drive in Sprocket Designer on ANSI 50 (the 530 motorcycle size) roller chain, 2 strands (duplex, both sprockets), about 500 mm between centres. Sprocket 1: 17 teeth, a sprocket; an ISO 4156 involute spline bore: module 1.25, 18 teeth, 30° pressure angle; a DIN 471 retaining ring on the top face, without a counterbore (the ring sits on the face); a splined washer under each ring; a hub on one side, 40 mm across and 28 mm long. Sprocket 2: 34 teeth, a sprocket; an ISO 4156 involute spline bore: module 1.5, 20 teeth, 30° pressure angle; a DIN 471 retaining ring on the top face, without a counterbore (the ring sits on the face); a splined washer under each ring; a hub on one side, 50 mm across and 30 mm long. Check the design, apply any Auto-fix it suggests, then export both sprockets and both sample shafts and the splined washers as STL and give me the download link.
