Farrier Tramp Scupper Plug

I designed this after I got tired of my kids accidentally kicking out the rubber stoppers I was using as scupper plugs on my Tramp trimaran. These plugs sit nearly flush on the cockpit side and incorporate a valve to let the cockpit drain if we take on a significant amount of water.

These plugs **must be printed in TPU to work properly** or the valves will not open.
