It’s a toothpaste/etc tube squeezer. Takes about a minute to cut in inventables 3/32 acrylic. The only interesting part is that I did a defocused (0.500 focus height) score just outside the tube slot to round the edge of the cut. Won’t insult people by posting an svg 
Might be another good thing to use up scrap. (And if you personalized it, might be cute no-brainer swag)
That defocussing trick is indeed pretty handy!
It really is. I’ve been using it to draw lines on wood, and the texture is kinda cool.
Has anyone tried it for large-area engraves? I bet you could go way down on the lpi.
Actually I’v made them in 3d for my Grandkids, its a bear with a wide mouth and the toothpaste tube goes in. They loved them!
Simple is good!
I really need one of those. 
(and not just for toothpaste - trying to get the Gorilla Glue out of the tube is a real pain in the tush!)
last night I was thinking about something like this, as I tried to get all of the cheese-goo out of a mac n cheese packet
Now I’m thinking about a fancy version where I cut some kind of curve that acts as a spring.
Nah
