Cast Resin Vent Plug

Surfboards and paddleboards require pressure equalization to prevent delamination from temperature changes. This project focused on creating a reliable vent plug that could be made with simple shop materials. Prior to this, we had been resin 3D-printing the vents, which worked great; however, it was costly and time-consuming.

First, a 3D-printed part is printed, then silicone is poured into that mold. Once cured, the 3D-printed piece is discarded. While working on a surfboard, extra resin (which normally is discarded) can be poured into the silicone mold. Once cured, it is popped out, cleaned up, tapped, and ready to go into the surfboard.
