🌀 Eldred’s Workshop: Modular Ventilation System for 3D Printer Enclosures & Workbenches (4” Hose Ready)

Take control of your airflow! This modular ducting system from Eldred’s Workshop is designed to help makers safely and efficiently vent enclosures, soldering stations, or airbrushing booths using standard 4” flexible ducting — all compatible with fans like the VIVOSUN AeroZesh VSVV-AZG4 inline duct fan.

This STL pack includes a complete suite of printable components to build a customizable, filter-ready ventilation setup.

🔧 Included STL Files:

HEPA Filter Housing – Encloses a standard HEPA filter for clean output air.

HEPA-to-Hose Adapter – Connects the filter housing to 4” (103–104mm) flexible duct.

Downward Angle Flow Connector – A gravity-assisted angled adapter to increase flow efficiency.

Duct Shutoff Valve – Manually closes off or redirects airflow between paths.

Y-Splitter Pipe – Splits airflow between two zones (e.g., printer + workbench).

Exhaust Vent Cover – Mountable exhaust end piece, great for wall or window exits.

⚙ Printing Recommendations:

Material: PETG, ABS, or ASA recommended for temperature & fume resistance

Layer Height: 0.2 mm

Wall Line Count: 3+

Infill: 20–40% depending on structural need

Supports: Only required on select pieces (marked in file names if necessary)

🧩 Perfect For:

3D printer enclosures (Elegoo Neptune, Creality, Bambu, etc.)

Laser cutters

Airbrush booths

Soldering fume extraction

DIY filtration projects

✅ Designed to pair with the VIVOSUN AeroZesh VSVV-AZG4 inline duct fan (4”), but should work with any similar 4” inline fan system.
