Pool Cover Clip for framed pool

I was tired of trying to stretch out the flimsy pool cover across my pool by myself. Print out one of these for each frame post and walk around the pool clipping the pool cover to each one.
Print as solid as you like. I used PLA for mine. Scale it to fit your needs.
You can drill a pilot hole into the metal posts and screw these on or you can use the flat holes on the side and zip tie it to your post.
