Ultimaker 2 foot with rubber foot

I wanted to get better cooling for my upgraded Ultimaker 2 go. The controller becomes very warm because of the hotbed and the door. I had rubber feet by Adam Hall from another project, so I designed the foot around them. The 38x25 rubber foot prevents the the printer sounds to couple in the table plate. You need M6 20mm screws to mount the rubber foot to the holder. A nut is not needed but I integrated a place for a one in the design. If you use a nut the screw must be 25mm long.
