This optimized TPU corner bump is designed to reduce painful encounters with sharp furniture corners in homes, workshops, labs, or office spaces. It mounts using adhesive (CA glue, contact adhesive, or strong double‑sided tape such as foam/VHB) applied to the flat inner seating surfaces.
Design Highlights
Adhesive mount: Flat inner L‑surfaces accept glue or double‑sided tape; just clean the corner, apply adhesive, align, and press in place.
Energy‑absorbing internal structure: Layered inner ribs/shells help manage deformation—firmer near the mounting area, more compliant toward the round outer dome.
Large smooth impact dome: Distributes force and removes sharp edges—ideal where kids play or where you brush past benches frequently.
TPU resilience: Flexible yet durable; won’t chip like rigid plastics when struck.
Print recommendations
| Setting | Recommended | Notes |
|---|---|---|
| Material | TPU ~95A | Softer grades increase cushioning; may need stronger adhesive. |
| Nozzle | 0.4 mm | Larger nozzles okay for faster prints. |
| Layer height | 0.2 mm | Up to 0.28 mm draft. |
| Walls | 3–4 perimeters | Structural stability + bonding area. |
| Top/Bottom | 4–5 layers | Good seal + flat surfaces for tape. |
| Infill | 0–20 % (Gyroid/Cubic) | Internal ribs already add structure; 0 % OK if ≥3 walls. |
| Speed | 20–35 mm/s | Improves TPU reliability. |
| Retraction | Low/slow | Reduce stringing. |
| Cooling | Moderate | Enough to hold shape; don’t overcool TPU layers. |
Safety Note
Corner bumpers reduce impact severity but don’t eliminate risk. Check adhesion periodically—especially in homes with toddlers who may pull or chew on protective parts.
