My son asked to have a Toothpaste Squeezer with Toothless from "How to train your dragon".
I found "Toothless-cookie-cutter (How to train a dragon)" by matschi to be an ideal base for my design.

I filled up (no longer a cookie cutter) and made several sections as holes, to give it more interesting look.

I used "Stormtrooper Toothpaste Squeezer" by Netsquash as inspiration, and my guide for how to design the Toothpaste portion, including sizes and spacing.

But in this design I added an extra slot so you can route the Toothpaste in both and won't come loose so easily.

NOTE: the Toothless figure is disproportionately big for the toothpaste holder. I was planning to make it smaller (much like in Netsquash's design), but my litle customer liked this one better so I left it as is.

I'm including the Sketcher file in case you wish to make further changes.
