4 inch flex dust collector hose quick disconnect

I needed a quick disconnect to be able to swap my dust collector from one mobile tool to another.  I could not find what I needed on PrusaPrinters, but I found one on another site that unfortunately did not fit properly.  I redid it to fit my hose and the tools.  The threaded part on the original had a square end the snagged the plastic, making it nearly impossible to attach it to the hose.  I fix that with a tapered end to the thread.  The part that fits over the port on the tool was way too big and had to be reduced.  I am providing the SketchUp (SKP) file if you want o modify it.

I will also be posting a dust collector port that will fit nicely with this quick disconnect.  I designed it for a tool that did not have one.
