Kayak or Boat plug
Description
This is a replacement boat plug that has an opening of about ¾" or about 19mm. It has a groove for grommet ¾" OD and 9/16" ID and 3/32" cross section. Since you print it handle down you will get a nice flat seat and may not need the grommet. Two varieties. My old plugs had a flat seat. I made a flat version and one that has a groove that fits over the flange at the entry. I don't know which is better. I would say the groove version has more surface making contact. On my original plugs they ether did not come with an o-ring or they would dry out in the sun (where I left them) and fall off. It never seamed to make a difference in terms of seal. ## Print instructions Print knob down with a brim so it does not fall over. No supports should be needed. I used PETG
