FEA — 500 N (112 lbf) Compressive Load

Static study representing a worst‑case downward force from overfill/impact. Von Mises stress (N/m²) shown at right; local peaks appear at fastener bosses with nominal stresses across the flared capture. PET geometry and fillets help manage gradients while maintaining stiffness.

Wireframe & Interfaces

CAD wireframe illustrating internal loft and locating nibs used for positive engagement with the Luup bin — they index on the rim to prevent slip‑out during opening/closing while still allowing easy removal for cleaning.
  • Width: 125 mm
  • Low‑profile wings minimize door interference
  • Material: PET (option for recycled content)

Design Notes

  • Capture geometry: Funnel guides rim; generous fillets reduce stress risers.
  • Mounting: Four fasteners distribute load; optional backing plate for particleboard doors.
  • Finish & Sustainability: PET with matte black; supports recycled content and end‑of‑life recycling.
  • User experience: One‑hand placement; smooth surfaces for easy wipe‑down.
