Dust collector for the X-Carve cnc machine. It is screwed in place with 3 screws, 2 on the motor and 1 on the spindle mount. This is for a 1 and 3/4 vacuum hose. Spindle mount needs to be removed to access the two screws from the bottom. Then I pushed the motor thru the spindle mount from the top so that about half of the motor is showing thru the bottom of the spindel mount (as show in picture). First screw the two screws to the motor then push the motor back to the spindle and screw the last screw to the spindle mount.
