Check valve for ventilation based on sewer pipes with a diameter of 110 mm.

I made ventilation by collecting it from 110 mm pipes used in the sewer.
I used these pipes for ventilation in the kitchen.

The previous version did not perform very well, the film lost its original profile from the warm air.

This version works very well.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
