Fan shaft router (Ultimaker)

What parts are needed for the shaft engines blowing. What is the direction of air flow from the fan up the shaft and sideways into the blowing grille. For whom is this solution intended - the owners of Ultimaker with a body material thickness of 6 mm (with air shafts). The standard design of the blowdown shaft of XY engines and extruders has two drawbacks: 1) The fan below blows perpendicularly into the wall of the shaft, thereby lowering the speed of the air flow and directing it into not the right direction from the very beginning; 2) Air is blown out of the shaft into the internal space of the printer, creating uncontrolled air flow in the printing area. Solution: 1) Fan blowing router right.stl (for the right shaft) and fan blowing router left.stl (for the left shaft) are installed on the bottom of the shafts opposite the fans. This detail changes the direction of the air flow, routing it up the shaft to the motors; 2) Channel cap right.stl (right shaft) and channel cap left.stl (left shaft) are set to the top of the shafts. This part prevents the passage of air from getting into the internal space of the printer, directing the flow into the blowing grille. Update: Have added channel cap right ext.stl - the right shaft cap corresponding to the size of the left one (to increase the level of aesthetics).
