I thought I'd post this as inspiration to others trying to accomplish clean routing with their miniature CNC router.
I have tried several approaches to a dust shoe, but they all tended to be bulky and limited my use of an already very small table. So I mostly directed a hose by hand (ugh!).
So I came up with this approach using some PVC pipe (Menards actually carried S&D in 3/4" pipe, which has a larger internal cross-section than schedule 40).
The air movement past the bit helps to cool the bit. I can touch the bit immediately after 20-30 minutes of use and it is hardly even what I'd call warm.
Nothing escapes while routing wood, anything launched by the bit is grabbed by the shoe.
I will probably make a second one with a brush bottom for when I work with aluminum as the aluminum chips can be trouble to contain.
This is all PVC. I used a 1" to 3/4" Tee to make the bit surround, two elbows, and the S&D. I had to do some minor trimming of the tee and elbows to make it all fit.
But I'm sure glad I don't have to hold onto that hose any more.
