About this model
I needed some ventilation for the tarp/cover of my boat I use for winter storage. The goal was to create something relatively easy to install, without any sowing.
The model pictured in the instructions below is printed with ASA (strong, cheap and weatherproof) using HIPS support, but any material will work.
Any feedback is highly appreciated. Let me know if any modification is needed for your project.

To prevent any small bugs from getting in, you could also mark and cut a piece of mesh. Use the outside of the ring
4. Screw the vent to the cover
Screw the vent loosely to the cover, and tighten when all screws are gripping the threads.
