aldi 'Fitness-Shaker' drink bottle sealing ring

thingiverse

This is a clever sealant for the Fitness-Shaker, which Aldi Nord introduced in Germany during the first week of 2019. Although the bottle itself isn't fully waterproof out of the box and may leak if dropped, like similar-sized PP plastic bottles tend to do, this issue can be resolved by adding a sealing ring at the end of the thread. The design is refreshingly straightforward, thanks to being proudly crafted with openSCAD. And what's more, my initial prototype performed so well that I feel confident sharing it with others.
