Priruba na vetranie, ventilation inlet flange

this is a flange to mount and additional inlet / outlet directly on a 150mm steel pipe of the ventilation system. the inlet / outlet diameter is 90mm and has an adjustable lid.

To assemble it you need an M5 threaded rod and three M5 nuts. Two of the nuts are inserted into the printed parts (one in the lid and one in the main body) and the third one locks the cover safely on the rod.

First you need to drill a hole of about 90mm into the original pipe. To install the body on the pipe I used double sided tape to fix it and covered the body all around with aluminum tape.
