Toothpaste Tube Squeezer Ring

I've been using a simple squeezer print https://www.thingiverse.com/thing:701833 by jessausage and it's been doing what a squeezer should do... up until we got tubes that were just a hair wider than the slot.

So ... I took a few minutes to draw my own design with a 62mm slot and shaped it to provide minimal center flex.
