I needed a vent cover for my pvc pipe in my mushroom grow chamber. So I made one in openscad. This is free for anyone to use, remix, make copys of, distribute, whatever. I have no qualms. Have at it if its usefull for you.
The following link should bring you to an online editable copy of this project. you should even be able to reder it and export an stl at the bottom left hand corner.
If you find anything I produce useful. Consider sending some love in the form of cash or crypto.
