BRITA mouthpiece replacement

This is my model of the BRITA mouthpiece replacement. It's printed in TPU giving it a soft and squishy feeling when used, it fits right inside the bottle cap the same way the original one does and it also prevents the water to spill out when the lid is cosed. Long story short, it's the original mouthpiece but designed and 3d printed by mysef. If you find any problems with it or you have any questions or advice for improvements, don't be shy and let me know in the comments! I hope it's useful ;)
