The prompt
Create a 3D-printable right-hand vectored intake wheel for an FTC robot. The maximum overall diameter, measured across the farthest outer surfaces of the rollers while the wheel rotates, must be exactly 32.0 mm. Use a central hub with a goBILDA 8 mm REX shaft bore. The bore must fit a genuine goBILDA 8 mm REX shaft: use a 7.0 mm hex flat-to-flat profile with rounded outer points inside an 8.0 mm maximum-diameter envelope. Add reasonable FDM printing clearance to the bore so the wheel slides onto the shaft but does not spin freely on it. Use free-spinning angled rollers arranged evenly around the hub, following the same directional behavior as a mecanum/vectored intake wheel. The roller axes must remain at a consistent diagonal angle. The wheel must vector game pieces sideways when driven. Use M4 screws as the roller axles. Design a 4.2 mm to 4.4 mm clearance hole through each roller. Use a captive M4 nut pocket or an M4 heat-set insert pocket in one side plate/support, and a counterbore or countersink for the M4 screw head on the other side. Do not use M4 threads directly in printed plastic unless a heat-set insert is specified. Include a practical FDM-printing clearance of approximately 0.3 mm on each side of every roller so they spin freely without scraping the side plates. Build separate printable parts: a driven hub/side-plate structure and individual rollers. Add a left-hand and a right-hand mirrored version. Keep all roller outer surfaces, screws, and supports within a maximum rotational envelope of Ø32.0 mm. Use at least 2 mm wall thickness around structural areas where geometry permits. Export editable CAD, STEP, and STL files. Before finalizing, verify the model with a section view and measure the maximum diameter across the rollers. If the wheel cannot physically fit the 8 mm REX bore, M4 roller axles, and rollers within Ø32 mm, tell me what dimension or hardware must change rather than silently exceeding Ø32 mm.
