3D printer ventilation system for window fit to 100mm aluminium hose

Ventilation system for 3D printer. Easy to hook to the top of opened window and connect to 100mm aluminium hose. Works greatly with QIDI plus 4 printer. Suggestion is to remove inside filter in the chamber, connect 100mm aluminium hose to the printer exhaust and another end to this ventilation system. No more smell and toxic air.

Could be printed from PETG or PLA. Construction consist of two parts. Print it as separated parts and glue them together, or print it all at once with support.

I did it by printing round part first, and next I printed hose laying on the side without support.

After finish I glued them together. 

Works perfectly with:
