Laghetto skimmer replacement - galleggiante skimmer Laghetto

This is a replacement for an old Laghetto skimmer.
My swimming pool is an old Laghetto branded one, almost 40 years!
2 years ago the top piece of the skimmer (the part that makes it float) broke and I fixed it with glue but it didn't hold long...
Due to high price of new skimmers I ended up printing a new top piece to make it float again.
It is divided into two parts with a thread to connect then. The inside is empty and has to be filled with some sort of foam, bubble wrap may be ok (I used styrofoam).

Here you can find a video demonstration: https://youtu.be/_bi0kBtoUSw

After around 3 months of use it is working really well.

I printed both parts with .3 layer height and PLA.
