I've seen these kinds of water bottle holders/drink holders online, but they're all too small to fit my girlfriend's water bottle.

Fix it on the baseboard and secure it with an elastic cord to prevent it from sliding or tipping over.

Therefore, I specially designed this holder, which can perfectly accommodate a water bottle with a diameter of 80 mm.

In order to increase the stability of the grip, I adopted a textured design on the surface and eventually reduced the outer diameter to 79 mm.

This stand is printed using PLA material.

I have also made other versions with ASA material, with a filling density set at 15%. This way, even if it accidentally falls, it can easily float to the surface.

Everyone just needs to readjust the size ratio according to their actual needs, and they can customize the version that best suits them.
