26 Dec 18 EDIT: The original model was opened in Autodesk Fusion to thicken the supports. The original object and the thickened version were added as f3d files.

Note: I recommend suspending the vacuum hose above the SO2. For example, I use a string tied to a rafter. If you drag the hose with this attachment, the drag force is liable to break the connection posts. Hopefully the thicker/filleted version will help with this issue.

Original Post:
I spent quite a bit of time trying to manage my chips and sawdust. I thought about using a piece of clear acrylic with skirting - I still think that is a good option. But I really wanted something that I could completely print. I have to admit that I saw a design similar to this somewhere in the ether of the internet. A few days later, still struck by inspiration, I designed this from scratch. I hope that no one out there is offended by my process.

This design produces an updraft that surrounds the endmill. With the motion of the endmill it creates a small vortex - really fun to watch. Also, the lights still shine through. I would guess that this get 95% of chips, though I haven't measured scientifically. I can tell you that all that remains is the dust in carved tracts and inside corners where the air doesn't flow. That and a very fine layer of the smallest escapees.

Fair warning, you won't be able to do deep plunges with this attachment - it will block your clearance angle quite a bit. Also, remember to account for your clamps. Other than that, have fun!

You will have to use internal supports for the ducting. Make sure to adjust your settings so that the internal supports will break away easily. I recommend lines, 15%, 1.5mm XY, 0.15 Z. Also note, I used PLA. It is plenty strong and hasn't been affected by heat from the DWP611. PLA supports break away more easily that PET for me. ABS might work but I can't vouch.
