Kids Toothpaste Squeezer

UPDATE: I have marked this a work in progress, as I have not been able to re-print this strong enough to work. Only the original prints lasted beyond fitting, but now those have broken after 2 months of use. Leaving it up here for ideas to the concept.

I have now remixed a new version, which should print much stronger
