Just a simple dust shoe for a 65mm spindle with a removable front for easy access to bit changes etc.
The vac hose adaptor is tapered between 30mm and 32mm. This will fit most shop vacs and home vacuum cleaners.

Supports are needed. I used cura and it took me less that 5 minutues to remove the supports.
