Review: Well made and fills a need. Support your local maker. - Well made for a basement 3D printed item. Works fine. Fair price. Filled a need perfectly, and I appreciate the ability to support other makers. Need: I do amateur digital electronics and solder at a bench in a home office a lot. I built a custom exhaust fan / vent setup using a home "grow" fan and shop vac 2.5" ducting. The fan and exhaust are 4". I exhaust everything out the window through a dryer fitting and baffle. The 2.5 ducting gives me velocity and 4" gives me the volume. It works well under my microscope / soldering stage.

Great product that works well. Fits over most dust collection ports.

### ⭐⭐⭐⭐⭐ This was not a perfect choice, but it did the job well.
*by D***M on January 8, 2026*

I would rather the 4 inch side was slightly larger, rather than the same size as the pipe, so that it would simply fit over the pipe to just be banded down, but the flex cuff accomplished that task. I was just happy to find a product that accomplished what I needed, which was to vent toxic fumes from a 3-D printer to the outside through a dryer vent.
