Qidi X-Max 3 Rectangle shaped exaust / Duct

I know this is not that usefull for most of the ppl but i want to share it anyway.

Since my printer sits in a corner, (i dont have that much space, from wall to printer. I only have like 6+cm on the back and the side, so a 80mm hose is too thic for me) i wanted a “slim” but non restrictive air exaust hose and i found a 55mm by 220mm hose on Amazon.

So i build a duct that mounts on the backside, on the exaust fan.
 

*U may need other screws.  

*see update below

You can turn it to your prefered direction.

Only downside is, u cant use the filament container on the backside if u have it in up or right orientation and u have to demount it, when u want to open the printer on the backside if u have another direction than upwards.

The whole body has a 1,5mm wall thickness and the hexagon shapes helps to withstand the mounting force with the clamp.

What u need to buy:
https://www.amazon.de/dp/B0899Y1SZ8 - 55x220mm Hose. Choose your preferred lenght
https://www.amazon.de/dp/B0C55FM1XD - to mount the hose on the duct 

Layer: 0,3
Material: PETG - Black
Walls: 4 - Arachne
Supports: Tree → see screenshot
Printtime: for me a little less 5h30m but i print slower (Its because of the hexshapes)

*UPDATE:

Yes, the part fits the hose mentioned above.
Yes, 4x selftapping M3 16mm works to mount it.

Unfortunately, i dont have the desired space between walls & printer and sadly i had to go down to a 40mm hose. 

At first i wanted the 55x220mm hose cause of noise production. The 55x220mm hose made near to 0 additional noise production even with exaust fan on 100%
The adapter did fit, but the hose did ony baraly fit between walls and printer. (Because of the natural shape of the hose,.. its not perfectly rectangle, it more like a bit oval on all sides and so it needs like 60-62mm in width)
But then i cant place my filament dryer next to the printer (limited space).
