Airflow redirector for Lefant M1 robot vacuum

This thing makes the air expulsed by the Lefant M1 robot going up instead of horizontally. The robot is great for vacuum (it sucks at water cleaning though), but like most robots, the air that it blows out goes horizontally. This makes dirt from areas that have not been cleaned yet move to areas that have been cleaned already, so there are still dirt after the robot has completed its cycle. So I made this thing for the air to be blown out upwards instead. Please note there are rational reasons for most vacuum to blow air out horizontally, like: Preventing light objects placed on furniture from being blown out and falling on the floor. This happens with that redirector, especially with small pieces of paper on the edges of tables. Make sure to prepare your rooms for that. Preventing dust from curtains or furniture from being blown out and falling on the floor, or flying in the air and be inhaled. The same is true for very small dust particles that have been sucked up by the vacuum cleaner but passed through the filters. Reducing noise. I don't hear a significant difference though. Printing I rotated the object for printing so that it won't break horizontally because of the tension between the bottom and top edges of the robot (see the 4th image from Cura). Installation Insert the round part into the screw hole at the bottom of the vacuum (see 3rd image) and clip the upper part to the top edge of the robot.
