AC (Mobile Air Conditioner) Sliding Door Seal Kit

I designed this seal kit for my mobile AC. So now all the air in my room gets sucked out withoud warm air coming in.

Its made specifically for my sliding door so may need to be adjusted to your specific door. 

Made for a exhaust tube with a diameter of 15cm (150mm).
I just 3mm bolts with nuts to tighten the plates together (so the holes are also 3mm).
