Mikrotik RB4011 Ventilation Stand

My RB4011 is located in a closet and gets quite hot without ventilation. This helps to cool it down with a slow running 12cm fan standing besides. RB4011 fits perfect on it, but it can easily be resized in the slicer for other equipment. Print instructions Does not matter wich filament you use, can be print facing down without brim an support. 20% infill is enough I have printed it with extruder PLA NX2 white
