What it does
- Connects your box fan to round 4-inch pipes so dust and fumes exit safely instead of lingering in your workspace
- Multiple spout and flange variations let you match your exact duct setup without buying several adapters
- Printed on demand just for you, so you get the right fit without waiting for stock or paying for options you don't need
Your workshop runs cleaner when air moves out fast. This 4-inch box fan adapter bridges the gap between your box fan and duct pipe, so you can pull dust, laser fumes, or exhaust straight outside.
You get design variations for round pipes, standard flanges, and different spout types. Pick the version that matches your setup. Print it on demand, and it arrives ready to install. No waste, no extra parts gathering dust on your shelf.
Works with full spectrum lasers, dust collectors, and general workshop ventilation. Snap it on, tape it down, and breathe easier while you work.

What it is made of
Designs like this print well in PLA. Compare the materials.
Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
