What are some of the projects you guys have made using the CNC for the CNC and dust management? Enclosures, vacuum attachments, grid surface bases, etc?
Would love to see some of your ideas and how they have worked for you.
Building my machine today and will need to get on this sooner than later.

I used my CNC to create an MDF vacuum clamping attachment. I got the idea from a Youtube video I'd seen about five years ago. I've tried to find it to link it here, but I guess it's no longer up. There are other videos that show similar projects, but they show the MDF vacuum plenum being used in conjunction with a vacuum pump or a shop vac. What was unique about this is it created good clamping vacuum using an old household vacuum cleaner. It clamped so well I even tested to see if it could be used for dust collection at the same time it was clamping, and it didn't do too bad.

My first Carve King machine I made basically a dust tent out of 1/2" PVC frame and a blue tarp. This was the same as an enclosure and I manually vacuumed the work bed between cuts. On the Mega V, I modified a dust boot design I found on thingiverse.com and 3D printed it all. Both have pluses and minuses. I think it's one of those things that you have to try and see what works with your process.
Do a search on "Dust Shoe" in the forum and you should find all kinds of examples.

My own fairly ineffective solution (in fairness, the Plague came, and suddenly I was a homeschool teacher for two years) was to cut what I call a dust ring -- a simple ring composed of two nesting rings which clamp a polyethylene brush I made out of laser-cut stencil sheet. The polyethylene sheet is clear, so I can see WTF is going on with the cutter (I still don't trust my gcode/CAM abilities), and has been slit so it forms a brush/comb. Two layers of the polyethylene are reasonably effective at capturing dust as long as it's not MDF dust, and then I stand there with a vacuum clearing out slots after the cutter passes by.
My rings attach to the Z mount with magnets, and the nesting rings were cut from 5mm ply.
One of my near-term goals is to add a blower port with nozzle to blow dust away from the cutting surface, and another (larger) port for a vacuum hose on the opposite side, which may require some 3d printing to make appropriate nozzles.
