🔥 Original Magnetic Three-Piece System Solves Closed Window Printing Exhaust Problems Designed for 100mm Ducts Easily Switch Between Open/Closed Window Modes

✨ Core Advantages

1. Magnetic Quick-Release Design
   • Three-component magnetic nesting (screen window external exhaust component + screen window internal bidirectional magnetic base + exhaust duct component)
   • The exhaust duct component can be easily removed when closing the window without affecting window closure
   • The exhaust duct component can be easily attached when opening the window for printing
2. Screen Window Friendly Installation
   • Adapts to common screen window thicknesses
   • Extended surface supports plastic bag extension
3. Precise Duct Adaptation
   • 100mm inner diameter industrial standard

To achieve the best magnet press-fit effect it is recommended that you first print this test model for verification Due to magnet tolerances and printing shrinkage you may need to fine-tune the hole positions using "X-Y Hole Compensation" in slicing software such as Bambu Studio/Orca Slicer
After adjusting to the appropriate size the magnets can be pressed in or glued With the aid of a vise or clamp you can ensure smooth magnet installation

⚠️ Safety Notice (Must Read)

• Magnet Reinforcement Suggestion: Fix with glue after embedding
• Anti-Detachment Measures:
→ 8 M1.6x10 screws and nuts are reserved for reinforcing the screen window inner base and outer connector component as needed
→ Safety Rope Anchor Point: 1 to 2 of the M1.6 holes can be used to tie a safety rope (connecting to the window frame or other securing equipment)
• Environmental Limitations: For strong winds/high-rise environments it is recommended to use N52 strong magnets + screws and nuts + multiple safety rope protections + regular inspections
• Magnet Specifications: Use N52 10x3mm neodymium magnets
