Pinter Cap with wing tabs

Pinter cap with wing tabs for locking onto the dock. 

I made this since the ones out there are just on there, this one will lock in place to prevent it from falling off if you store your docks on their side. 

Print with the opening up so the finish is  smooth and doesn't damage your gasket

It's best if you use PETG for some flexibility but PLA will work just fine. 

20% infill

 supports needed

you can print at an angle for a better finish on both sides.
