This version is a high-speed, material-saving design specifically created for use as a dust protector for vintage electrical junction boxes.

• Design Concept: Hollow-core architecture to minimize print time and filament consumption while maintaining structural integrity for light usage.
• Dimensions:
  • Major Diameter: 80.5 mm (Designed for an 81.0 mm internal box diameter).
  • Plate Diameter: 87.0 mm (Full coverage for the box rim).
  • Thread Height: 7.0 mm (Ensures a secure grip with multiple rotations).
• Thread Profile:
  • Type: Fine Thread.
  • Pitch: 1.0 mm.
  • Entry: Integrated Chamfer for easy alignment and cross-thread prevention.
• Optimization Features:
  • Wall Thickness: 1.6 mm (Optimized for 4 perimeters with a 0.4 mm nozzle).
  • Hollow Core: Removes unnecessary internal volume to slash print time by approx. 40-50%.
  • Ultra-Thin Plate: 1.2 mm thickness, sufficient for dust protection.

Recommended Print Settings for Bambu P1S:

• Layer Height: 0.16 mm (Optimal balance between speed and thread precision).
• Infill: 0% (Not required due to the hollow-core geometry).
• Wall Loops: 2 to 3.
• Material: PETG (best for basements) or PLA (standard indoor).
• Estimated Print Time: < 15 minutes.
