Window Duct Adapter 125 mm / 5-Inch Duct Version – Digital Files for 3D Printing | Fume Extraction, Grow Tent Exhaust, Tumble Dryer Vent, AC

Tilted Window Duct Adapter – STL File for 3D Printing | 125 mm / 5-inch duct version

Need to vent air through a cracked or tilted window? This 3D-printable U-shaped window adapter is designed specifically for 125 mm (5-inch) ducting and offers serious airflow capacity in a space-saving form factor. Ideal for indoor growers, makers, apartment dwellers, and workshop users who need a clean, easy, and modular solution.
✅ What’s Included:

STL file for U-shaped window vent body (optimized for 125 mm ducts)

STL file for 125 mm duct adapter ring

15 mm overlap interlock with 0.3 mm clearance for secure fit

Designed for two M3 screws (or glue-in) for fastening the duct ring

Prints support-free on FDM printers—designed for strength and ease of use

🛠️ Print Info (Solid Print Example):
Part Filament (Solid) Print Time (Bambu X1C)
U-shaped duct ~600g ~18 hours
Duct adapter ~230g ~8 hours
Total ~830g ~26 hours

You can adjust wall count and infill to suit your needs—this model is rock-solid when printed thick, but lighter-duty applications can reduce material/time significantly.

🧰 Use Cases:

Grow Tent Ventilation – exhaust fans or carbon filters venting outdoors

Laser Cutter Fume Extraction – perfect fit for home laser enclosures

Portable Air Conditioners – create a functional exhaust path in tilt-open windows

Tumble Dryer Exhaust – great solution for venting in small apartments

Workshop Air Management – redirect fumes or dust from enclosed CNC, soldering, or resin printing setups

⚙️ Compatibility:

Designed specifically for 125 mm / 5-inch ducts

Compatible with flexible ducting (aluminum, vinyl, plastic)

Adapter ring fits into U-duct with friction lock + 2x M3 screw fastening

PETG, ABS, ASA recommended for durability and heat resistance

🔑 Features:

Modular design – swap or customize the duct ring for your setup

No supports needed – optimized with max 45° overhangs

Slim U-shape profile – fits in narrow tilt-open windows

Print-tuned interlock – secure 15 mm overlap with 0.3 mm fit

Easy to install & remove – renter and DIY-friendly

🖨️ Recommended Print Settings (For Most FDM Printers)

These settings are aimed at balancing strength, dimensional accuracy, and print success—particularly for this large-format, support-free duct adapter design.
🔧 General Settings:
Setting Recommendation
Nozzle Size 0.4 mm (standard) – larger nozzles like 0.6 mm can reduce print time for heavy-duty builds
Layer Height 0.2 mm (standard), or 0.28 mm for faster prints
Wall Count 6+ (≥2.4 mm thickness), or more for extra rigidity
Top/Bottom Layers 4–6 depending on infill
Infill 15-30% Grid or Gyroid – adjust for intended use
Material PETG or ABS preferred for strength and heat resistance (PLA works but less durable)
Print Cooling On for PETG/PLA – Off or minimal for ABS
Bed Adhesion Brim or skirt recommended – large flat part area
Supports ❌ None required – part is designed to be fully support-free
Build Volume Needed ~220 x 220 mm minimum (or diagonal placement)
🧱 Filament Usage & Print Time Estimates (125mm Version):
Part Filament (Solid Print) Time Estimate
U-Shaped Duct ~600g ~16-20 hours
Duct Adapter ~230g ~7-9 hours
Total ~830g ~23-29 hours total

📝 Users can reduce wall count, use lower infill, or scale down slightly if not used for high-pressure airflow.

💡 Pro Tips for Best Results:

Tune bridging settings: Keep bridge speed low (20–30 mm/s) and enable "bridge flow rate" settings for cleaner undersides.

Z-seam alignment: Set to "random" or hide at corners if visible lines bother you.

Filament color: Light colors show less blemish if bridging slightly sags.

Dry your filament: Especially for PETG/ABS—moist filament affects layer adhesion and bridging.
