My custom Bambu Lab A1 stiffener design without additional screws

Key Features:

• Increases frame stiffness and overall printer stability
• Reduces vibrations and resonance artifacts
• Improves surface quality and dimensional consistency
• Designed specifically for A1
• Easy installation using standard mounting points
• Optimized geometry for FDM printing
• Uses only the ST3-8 screws included with the A1
   

Printing Recommendations:

• Recommended materials: Bambu Lab PLA Basic, Bambu Lab PETG HF
• PLA Basic works well for maximum stiffness
• Layer height: 0.16–0.20 mm
• Perimeters: 3–4 walls
• Infill: 15–20% (Gyroid recommended)
• Supports: Not required
• Just use my profile to print 😉
• Recommend always drying the filament before printing for better results!

Bambu Lab A1 stiffener Short version print profile:

• The short version of the stiffener does not protrude beyond the table (along the Y-axis), allowing additional space to be saved.
• Added a profile that allows printing a colored Bambu logo (using AMS)
