Remixed from the Sourcream Squeegee I came up with. Gap had to be increased due to the packaging for toothpaste is a bit thicker, 1.5mm seems to work pretty well.

Four lengths to accommodate different packaging. I do get a bubble of air space above the squeegee, probably just a side effect of an air pocket during the packaging process.

Got some feedback that these work well on tubes of paint like an artist would have sitting around.
