True Fruits Drink Bottle Cap

June 30, 2024

3D printed plastic cap screwed on top of a smoothie bottle. The wide mouth piece extends from the cap as well as a smaller mount, where the lid hinges in. The lid is pressed into the mouthpiece, closing the cap.

Warning: Use at your own risk! Unless you somehow smoothed the layer lines, it is advised to not drink hard water, or liquids that contain sugar, as the mouthpiece might be hard if not impossible to clean properly.

Description

Bottle cap for a 750ml true fruits smoothie bottle.

Great if you want to use an empty True Fruits glass bottle as your daily-driver drink bottle.
In contrast to my original closed cap, this model has a mouthpiece and lid, which allows you to drink directly from it, without having to unscrew the lid.

The same cap, but with the lid hinged open, revealing a rubber gasket around the lids inside and a bevel edge inside the mouthpiece

Requirements

Printing

Simply download the stl file and slice it using your favourite slicer.

Both parts can be printed together in one go, exactly the way they are positioned in the stl, without the need for support.

The cap and lid sitting next to each other, the way you would print them

Assembly

  1. Take the printed cap and turn it upside down
  2. Place the larger O-Ring around the inner cylinder core

  3. Take the 3d printed mouthpiece lid and turn it upside down (the same orientation as in the stl file)
  4. Place the smaller O-Ring around the cylinder that fits into the mouthpiece
