Printable vent screw for stand up paddleboards*. It probably needs some o-ring grease* to get a watertight seal. I printed it at 100% infill. These don't have any cuts perpendicular to the threads, so they probably wont vent as rapidly as some of the others when partially loosened. I made these so I don't have to use surf wax next time I misplace my vent plugs.

I think there are a few different thread styles so I'm not sure which boards this design will fit. This design has a 1.5mm pitch and threads are approximately 12mm in diameter. The slot is sized to be tightened using a quarter.

I also added a threaded vent plug holder, made for attaching to a leash.
