Description
A high-strength, anti-slip replacement bracket designed to support heavy loads over 100kg (220lbs).
By leveraging TPU 90A, this design provides the perfect balance of compression strength, shock absorption, and high friction against the door frame to prevent slipping. Fully tested and printed on the Bambu Lab A1 mini.
⚠️ CRITICAL FOR STRENGTH: Do not use standard profiles. Follow these structural settings to ensure it handles 100kg+ safely.
| Parameter | Recommended Value | Note |
|---|---|---|
| Filament | TPU 90A or 95A | Do NOT use PLA/PETG (Too brittle & slippery) |
| Wall Loops | 5 - 6 | Crucial for perimeter and load strength |
| Top/Bottom Layers | 5 | Increases overall compression resistance |
| Infill Density | 45% - 50% | Higher density is required for heavy loads |
| Infill Pattern | Gyroid | Best for absorbing multi-directional stress |
| Print Speed | Slow (20-30 mm/s) | Prevents jamming and ensures perfect adhesion |
