Shower Head Replacement Button

This is a replacement button for my Shower head when the original broke at 12 months. Rather than recreating with the slot to put the rubber friction pad in which is a really bad design I made it solid (contoured for the pipe it has to grip). I made mine in PETG based on the theory that it will grip better than PLA or ABS. It seems to actually work better than the original ever did (but it is early days).

I don't know how universal this part is between brands (my Shower Head is a "Flexistream" brand but as it is a cheapish import it may apply to others) however it may work for you.
