Exhaust air pipe cover

Every homeowner is familiar with these plastic covers that lead from the cellar to the outside. They are usually used for the tumble dryer or as a simple ventilation pipe. After a few years in the weather, they quickly become brittle and break.
This model is intended as an inexpensive replacement. There are two sizes. One for 100mm pipe diameter and a second with 125mm pipe diameter.

Important!

Carefully measure the actual diameter of the installed pipe. Then scale the entire model to fit the measured value. In my case, the pipe had a diameter of ~101.5mm.

Both models have an integrated fly screen to keep insects out.
The model is easy to print and requires no support structures.
