Dust Extraction Nozzle 4 in

thingiverse

This is a 4 inch remix of https://www.thingiverse.com/thing:4237939 that was only 2.5 inches. I needed a bigger one for my dust extraction unit but liked the shape for clamping down to drill presses and similar flat surfaces. I did redo the entire thing in Fusion using the basic shape and dimensions of this one I remixed from, scaled to 160%, because I wanted to make it smoother with less flat surfaces inside to improve airflow and to reduce the needed supports.
