TODO: The hole for the tightening screw needs to be slightly enlarged. It is barely too small for the head of the 10-24 screw. The screw will work and fit, but depending on your printer's accuracy, and material, it may split the print slightly.
Dust shoe for an 80mm spindle.
This is a dust shoe that will clamp onto an 80mm CNC spindle with a shopvac-style vacuum hose attachment. It is two pieces that are attached magnetically which allows you to remove the brushes and change bits without removing the whole assembly.
This was originally designed for the 24x48 CNC Shark HD with water-cooled spindle.
There are 3 magnets holding the top to the bottom that measure 12mm x 3mm.
Vacuum Mounting Holes are designed for this vacuum hose adapter:

The magnets were purchased from Home Depot a while ago and I don't have the exact information. Search for 12mm x 3mm magnets and they should work.
Once the parts are printed, epoxy the magnets into the holes, insert the threaded inserts, and attach the vacuum adapter. Brushes should be glued slightly and press fit into the groove.
