Thingiverse
I added one to work with a 6mm pipe and trimmed the front a bit so the cover can go on all the way. You can pair it with this remixed shroud: https://www.thingiverse.com/thing:7301440, cover https://www.thingiverse.com/thing:7301454 and 6mm tube https://www.thingiverse.com/thing:7301458.Another remix one to use the pipe from Creality Air Assist Kit for Laser Engraver Falcon 10W, 22L/min Airflow Air Assist Pump for Laser Cutter and Engraver, Clean Surface Smooth Edge, Remove Smoke/Dust, Protect Laser Lens and use it for the window so it can exit out the front. You can put the cover on with the pipe attached. I was able to work it and get it tight by pushing and twisting. Should work with 6mm dust cap: https://www.thingiverse.com/thing:7301458.
