So funny @ezambob I came up with similar (but smaller) version of what you did. I used 3D printed adapters for those hoses just like you did (are yours 3D printed?)
I ended up abandoning that idea in favor of this one:
This had some advantages for me… and for our users:
-It doesn’t rely on 3D printing
-It’s lower profile so you get some more Z clearance (probably more of an issue with our deployment mechanism than on your setup)
-You can build it with a 2x4 sheet of plywood
The idea is that you can fasten it down to your table and hang the dust port off of the end of the machine on either end. For smaller machines like 4x2s you can hang it off the back or the front and still be able to reach the entire honeycomb with the laser.
I have the 4" hose run into one of these fans:
I actually have the fan plugged into one of the relays in my control box so it fires up automatically when I start a job, and back off when I am done. I have the duct run outside my shop. It does a surprisingly good job at removing smoke.
Now that you all know we just launched a laser I am thinking of open-sourcing this design so that folks like yourself can make it. (You’re welcome to download and use this one if you want)
