this is one of those things that when it breaks you would like to have immediately available, and it is precisely for this reason that I designed it, it was broken and in 5 minutes I had 4 new ones, and you know what? They have been mounted for 3 years and are still there. you can print them in TPU but also in pla, they are very resistant.
here you will find two versions, I hope one is suitable for your toilet, but you can always change the dimensions according to your needs
Thanks if you like
