Printing Recommendations

• Material: * PLA: Good for indoor vents.
  • PETG/ASA: Recommended for outdoor use or vents near heat sources (radiators).
• Orientation: The model is pre-oriented to lie flat on the build plate.
• Walls/Infill: Use at least 3 walls for the pattern strength. 15-20% infill is sufficient for the frame.
• Supports: Generally not required. Even the 45° slats are designed to print cleanly on most modern printers.

Please note: While the model is mathematically perfect, final dimensions may vary depending on your printer's calibration, slicer settings, and material properties (such as plastic shrinkage). It is recommended to perform a test print or adjust the dimensions slightly if you require a very high-precision fit for specific materials like ASA or ABS.
