Self Draining Scrupper - Kayak

One of my fishing Kayaks is lower in the water and I always have water in the copit, so made this self draining scrupper, which works really well.

You will need to resize it to fit your Kayak.

V2 was too small so I used duck tape to increase the dimension and get a nice seal.

Next version will be flatter at the top to give more drainage.

V5 is split so you can print the ball and remove the supports. Resize the top or bottom by 1.5% (up 101.5% or down 98.5%) in your slice program so that it fits together easier and then use some duck tape to keep the parts together and get the right fit into your Kayak. I find it best to print the top at 100% size and reduce the bottom to 98.5%.

V6 has no rim as shown in the photo. Let me know if you would like me to upload the file.
