I just got done building an enclosure for my MPCNC and I would like to pass through my dust collection hose and don know a good fitting to go through 3/4" plywood and also step down to a smaller hose for dust collection. There is about 4" of clearance for the z axis in the enclosure and about 2.5" on either side of the machine.
I was thinking of just using a 4" flange on the side for fume extraction.
I’m open to suggestions, links and thingiverse “things”
You can use this if you just want to suck the dust out of the air.

If you want to try to step it down to a hose to go to a dust shoe, you can use this:
I’m using the second one. I have the step down outside of the box, then I just shoved the 2.5" vac hose through a hole in the side of the box. I did a big coiled loop inside the enclosure and used a loose zip tie to hold the hose near the top in the middle of the box so the Z assembly isn’t holding all the weight of the hose.
Thanks. I was looking at the second one.
I hope you’re not pulling dust/chips straight through that fan assembly. It’s not made for that.
You’ll see in the pictures that I have dust collection and fume extraction.
Cool. I saw the duct booster and thought I’d throw out a warning.
thanks man!
Just curious, how does air get into your enclosure?
There is a space just below the doors in the front (3/4”) and there is a hole in the back (2”) from a previous shop vac setup.
