Air Purifier Dome

I bought an air purifier from amazon, so I'm satisfied with it, but it bothers me that the filtered air is only blown upwards without being able to influence the air flow.
Devices like those from Dyson have setting options for this, which I thought would also be conceivable in a similar form. With this in mind, I designed an attachable dome with adjustment flaps and, since the size couldn't be different, printed it out in two parts. I then glued the dome halves and inserted the flaps into the dome using a 6mm rod.
There is definitely still room for optimization, but that's enough for me for now.
The dome halves have to be printed with support, but printing also takes a lot of time.
To get the right side of the dome, simply mirror the left half of the dome in the slicer.

ich habe mir bei amazon einen Luftreiniger gekauft, damit bin ich soweit zufrieden, mich stört aber, das die gefilterte Luft lediglich nach oben abgeblasen wird, ohne das ich auf die Luftströmung Einfluss nehmen
