Fits regular crest toothpaste tubes. If there is a problem let me know plz, or if there is another thread size you want please let me know in the comments.
Inspired by https://www.printables.com/model/1156791-dwayne-the-rock-johnson-toothpaste-cap (note no assets were used from this model).
The author remixed this model.
Added an M14x1.5 thread to the inside and a loft, to create a toothpaste cap that spits out toothpaste. Fits on regular Crest tubes
