The prompt
You are a mechanical design engineer specializing in 3D printing. Design a cup holder that clamps onto a school bus seat top and holds a 24 oz tumbler. ## Mounting The clamp must grip a school bus seatback top edge ranging from 3" to 3.5" thick and hold securely under vehicle motion and vibration. Use a screw clamp, spring clamp, or ratcheting jaw mechanism that accommodates the full thickness range without loosening. Account for material fatigue in PLA, PETG, or resin across repeated use. ## Cup Holder Securely fit a 24 oz tumbler (3.3" to 3.5" diameter). Keep the holder low to avoid interfering with sightlines or aisle clearance. The tumbler should sit deeply inside the holder walls for stability. ## Deliverable Provide a complete part design integrating clamp and cup holder into a single unit. Include critical dimensions. specify parametric clamp opening range (3" to 3.5"), cup holder inner diameter, depth, and height above seat top. Design for 3D printing in PLA, PETG, or resin with optimized wall thickness and support features. Generate a 3D model file compatible with Sloyd, Meshy AI, or Tripio for direct export and printing, or provide component dimensions in CAD-ready format (SolidWorks or Fusion 360 syntax) suitable for import into those tools.
