Toothpaste saver

Say hi to the toothpaste saver! I made these to fight plastic waste. They fit the tube opening of Colgate, Solidox, Sensodyne and probably many more.

For years they've made us use too much toothpaste. At some point, they decided to double the size of the tube opening… doubling sales AND WASTE!
but relax… I’ve solved it. They will sell half as much from now on:-)
These 3D printed caps can be inserted and reduce the opening to 4mm. A pea-sized dab of toothpaste is all you need. The cap can be reused for your next tube.
Please share and cut the plastic waste from toothpaste tubes in half!
Design like you give a damn! Break the profit monsters greedy plan!

Please share!
