Sailing boats typically have plastic or rubber cylindrical covers for the lower part of the shrouds and stays (the wires that hold up the mast). These covers are called "Turnbuckle Boots".

Turnbuckle boots should be topped off with caps, but it is quite common to see the caps broken or missing entirely.

This thing is a replacement for those caps. It is fully parametric and printed perfectly without support.

See pictures to see the printed result on my boat.

Chris, I am in the UK and need replacement caps. Have you any idea who produces these? Most of the caps on the boat are fine but one just fell apart today. I don't want to replace the whole cover, unscrewing the turnbuckle and so on.....your help much appreciated.

Sorry no, I would suggest you google "turnbuckle boots uk", suppliers of those will probably offer the caps as well. Other than that, contact a local rigger - they'll recommend somewhere.

Wonderful idea, glad to see this featured. I don't currently have a boat, but I hope to someday!

 I think this is called a "Turnbuckle Boot" but i'm not certain.

The "turnbuckle boot" seems to be the term for the whole cover, so I guess it would be a "turnbuckle boot cap"!
