4" Window air duct for P1S

Translucent 4" Window Duct Adapter

Description:
I wanted a clean window adapter for my printer exhaust that didn’t block sunlight and was easy to print without tons of support. The translucent PETG also makes it look less like a brick in the window.

Infill Experiments:

• 🐝 Honeycomb → Best rigidity and load resistance.
• 🔲 Cubic → Most thermally efficient, about 0.6–1.0 °F better insulation than glass.
• ⚡ Minimal infill → Highest light transmittance, but bends inward (still strong enough to survive a window slam).

Print Configurations:

• Version A → Minimal support required.
• Version B → Consistent infill direction for a uniform look (needs more support).

Magnet Mount Option:

• Holes added at Layer 26 for 3 mm × 17.5 mm magnets.
• Magnets work, but aren’t super strong — double-sided tape is recommended for a more solid seal.

Notes:

• Fits standard 4" ducts (link in description).
• PETG translucent chosen for strength + light diffusion.
• Simple design avoids heavy tree supports while staying practical.

Print Settings (recommended):

• Material: PETG (translucent preferred)
• Layer height: 0.2 ~0.28 mm
• Infill: 5–15% (Cubic or Honeycomb) More just waste material  but gives finer infill detail
• Perimeters: 3–4 walls for strength 
• Bed temp: 70–80 °C (PETG)
• Nozzle temp: 235–245 °C
