Prompt
Create a dimensionally accurate 3D CAD model of a compact right-angle spiral/helical bevel gear pair, suitable for STL/STEP export. Use millimeters. The large gear must have exactly 40 teeth with outer diameter 60.000 mm, pitch diameter 59.215 mm, root diameter 58.234 mm, center bore 8.000 mm through-hole, face width 5.000 mm, pitch cone angle 74.624°. The small pinion must have exactly 11 teeth with outer diameter 19.139 mm, pitch diameter 16.284 mm, root diameter 12.716 mm, center bore 8.000 mm through-hole, face width 5.000 mm, pitch cone angle 15.376°. Gear ratio is 40:11, shaft angle 90°, pressure angle 20°, module 1.480 mm, spiral angle about 30°. Use opposite spiral directions so the gears mesh correctly. Create curved spiral bevel teeth, not spur or straight bevel teeth. Add small backlash 0.10–0.20 mm, smooth root fillets, and slight edge chamfers. Place the large gear on the vertical Z-axis and the pinion on the horizontal X-axis, with both pitch cones meeting at one com. apx
