Geeetech A20 120mm fan conversion and riser legs

Love the A20, really dont like the howl of the board cooling fan so fitted a 120mm fan, now its almost silent. The fan mounts directly to two of the bottom cover screws, cant believe my luck, just need some longer M3 screws. Then had to make some legs to lift the A20 clear of the table for the fan and air flow. I made it so the rubber feet can be reused, you might be able to wind the rubber feet screws directly into the legs or they may have to be tapped out M5. Then just some short M5 screws to attach the legs to the base of the printer.
