I have one for ATC; SUBNOIZE: 10 Tool Carousel, Tool Length Sensor and Dust Manifold
There is another guy 3D printing them somewhere. I tried the plastic thing and it melted on me 
so mine is 0.25 steel plate laser cut with a lower part 3D printed that doesn’t come into contact with the spindle. That was my most expensive crash 
Most people use the term “dust shoe” because the manually take it on and off i guess so search for that.
