The prompt
Create a functional 3D CAD model of a beach umbrella sand auger anchor with a side-mounted manual crank mechanism. The product should be a compact, minimalist beach umbrella anchor designed to drill into sand using a side crank instead of a traditional T-handle. The design should include: 1. A vertical cylindrical umbrella pole sleeve at the top. * Inner diameter: 40 mm * Outer diameter: 52 mm * Height: 120 mm * Include a side tightening knob/screw clamp to secure the umbrella pole. * Add a rounded collar at the top opening. 2. A sealed gear housing directly below the pole sleeve. * Shape: rounded rectangular housing. * Approximate size: 110 mm wide × 75 mm deep × 70 mm tall. * The housing should contain an internal 90-degree bevel gear concept connecting the side crank to the vertical auger shaft. * Show the housing as solid with a removable service cover plate and visible screw heads. * Add subtle seam lines to indicate the housing cover. 3. A side-mounted fold-out crank handle. * Place the crank on the right side of the gear housing. * Crank arm length: 90 mm from center. * Handle grip length: 70 mm. * Grip should be cylindrical with rounded ends. * Crank should appear foldable or compact, with a hinge joint near the gear housing. * The crank should connect into the gear housing through a circular bearing boss. 4. A vertical drive shaft running from the gear housing into the auger. * Shaft diameter: 18 mm. * The shaft should visually align with the center of the pole sleeve. * The shaft should rotate independently inside the outer body. 5. A spiral sand auger screw at the bottom. * Auger length: 380 mm. * Auger outer diameter: 95 mm. * Central shaft diameter: 18 mm. * Spiral flight thickness: 4 mm. * Spiral pitch: approximately 80 mm. * End tip should be pointed or tapered for easier entry into sand. * Auger should look strong but lightweight. 6. Add a small stabilizing foot plate or hand grip near the lower body. * Two small opposing foot tabs just above the auger, each about 70 mm long. * These tabs help the user hold the anchor steady while cranking. * Keep them rounded and low-profile. 7. Overall design style: * Minimalist consumer product design. * Durable beach accessory. * Rounded edges, no sharp corners. * Suitable for aluminum, stainless steel, and reinforced plastic parts. * Gear housing should look sealed to protect from sand. * The product should look realistic, manufacturable, and compact enough to fit in a beach bag. 8. Include exploded-view-friendly details: * Show separate material zones: metal auger/shaft, plastic gear housing, rubber crank grip, metal tightening screw. * Add small bearing collars at the side crank input and vertical shaft output. * Do not add electronics. * Do not create a large wheel; use a fold-out side crank instead. Generate the CAD model as a clean product assembly with accurate proportions, centered alignment, and smooth fillets.
