I needed a new cap for my bootle, so i decide to do it on my own with a original cap which is in metal, which gets rusty at the end, so i needed something less degrading.

So, it fits on bottle from 750 cl to 1L so the top of the bottle ø mm is inbetween(36.90-38mm)
the bottle cap has ø 50mm (to be exact 49,77), 9mm thickness and the walls are 1.75mm.
I tried to stay as close as possible from the original one.

I printed it in PETG CF and it shrinked and its nice because it fits perfectly my bottle.

Model made in Blender 4.0
