Servo controlled nozzle cleaning brush

Since my hotend cannot move off the heatbed I need to have the nozzle brush above the bed when cleanng but off the side when idle.

Be aware that the length and angle of the arm holding the servo is specific for my printer, so you may need to modify the attached fusion 360 file.
The mount of the arm is for a 2020 extrusion using 2 2020 t nuts and 4mm screws.

Just cut of the the handle of the brush to size. And the arm that folows with the serve is glued onder the brush holder and screwed to the servo
