Water Bottle Button

Designed this replacement button to replace the cheap injection moulded button that wears out and breaks. I'd much rather fix it than throw a good water bottle away.

I've added extra support on the button, it grips a little tighter than the original but is holding up well after 3 weeks of testing.

I've tested this on 2 types of these bottles but lots exist under different brands.
I've personally tested Proworks and Super Sparrow.

I think these bottles have rather loose tolerances in the factory but the two above work well.

You still need the rest for the assembly, I'll add the flap and the insert at a later date once I have tested them.
