The prompt
Create a fabrication‑ready technical drawing set (TOP, SIDE, BOTTOM, SECTION VIEWS) of a front‑wheel module for a scooter deck. REMOVE the existing head‑tube housing and REPLACE it with the following new housing assembly: 1. Cylindrical head‑tube housing: - Outer canister shell: 4.0 mm wall thickness - Outer diameter: 3.00"–5.00" depending on structural interpretation - Internal support ring: Ø 2.50"–2.75" - Head tube bore: Ø 2.00" - Deep bearing pocket above and below the bore - Vertical support walls (4 places), 4.0 mm thick - Radial reinforcement ribs (4 places), 0.25" thick - Reinforced rib + ring core tying the head tube to the outer shell 2. Show the housing centered EXACTLY over the front wheel centerline. ADD the complete front wheel and fork assembly: 3. Wheel: - 5.0" hub‑motor wheel - 3.0" wheel width - Wheel passes upward through a circular deck cutout Ø 4.00"–5.25" - Show hub motor body, axle, and mounting geometry 4. Fork assembly: - Fork shaft passes through the head tube bore - Upper and lower bearings seated in the deep bearing pockets - Fork crown below the head tube - Fork legs connecting to the hub motor axle - Show fork angle (1.5°) and head‑tube angle (72°–73°) 5. Deck interface: - Deck thickness 0.50" - Deck top surface 3.0" above ground - Show wheel cavity, underside ribs, cross ribs, and load paths - Show wheelbase reference lines (front and rear wheel centerlines) REQUIREMENTS FOR ALL VIEWS: - Draw TOP, SIDE, BOTTOM, and SECTION A‑A through the centerline. - Label all parts: Head Tube, Housing Shell, Support Ring, Radial Ribs, Vertical Walls, Fork Shaft, Bearings, Fork Crown, Fork Legs, Hub Motor, Wheel, Deck, Cutout. - Dimension every feature. - Show load paths and structural reinforcement. - Ensure the head tube is perfectly centered over the wheel.
