55mm Brushless spindle magnetic dust shoe

This is a vacuum attachment / dust shoe for 55mm spindles. I press fit (two stacked per hole) (8) 2mm x 8mm rare earth magnets to each side of the attatchments (16 magnets in total) mind the polarity. These could also be epoxied.

then attach the top part to the spindle with m4 screws, i used socket cap.

my specific spindle is:
