I finally got the dust shoe designed and 3D printed. It is installed and working great. I use a shopvac for dust collection so here is a link to the hose i use.
I used the McMaster brush part # 7900T2.
They do have 1" and 2" also.
These are the magnets for the upper part.
In the lower part it just uses 1/4-20 SHCS 5/8" long.
I used a few bungee cords to hang the hose.
Here is the link for the 3D printer files.
