The prompt
Create an assembly in mm using two components: 1. A flexible steel track, 60 mm wide and 2 mm thick, with repeated obround slots 6.5 mm long, 5.5 mm wide, and 17.95 mm initial pitch. 2. A drive sprocket with a 92 mm disc, 8 mm disc thickness, 30 mm hub diameter, 20 mm total hub length, and 12 mm central bore. Add 14 spherical studs, each ball 6.35 mm diameter, arranged on an 80 mm pitch circle. Position the sprocket beside the track so the spherical studs engage the slots. Keep components separate and dimensions editable. Show an isometric assembly and an exploded view. Check for interference. All dimensions are preliminary.
