thingiverse
This is a sealing ring for the 'Fitness-Shaker' aldi nord (germany) offers in first week of 2019 The bottle isn't really waterproof out of the box and may dropping, like other bottles of this size in PP plastic do too. However this one can be fixed by adding a sealing ring at the end of the thread. It's a very simple 'design', proudly done in openSCAD. And first triel was already working so well that I think I should share it.
