When it rains in the winter, it's possible for the pool skimmers to get more water in them than we want. I decided to be extra safe and make easy to use plugs to fill the holes during the winter.
I included the parameterized Fusion 360 file so you can tweak them for your own skimmers.
Mine are made by Sta-Rite. I can get the model number off of them if anyone wants that.
I printed them in TPU, though they may work with other materials.
They kinda look like pacifiers, I know :)
The author marked this model as their own original creation.
