This sleeve makes it so kids have to suck the food out of the pouch instead of squeezing out too much. Pouch goes in / out easily and snaps into place.

I designed this for a kid with motor problems that has a tendency to blast food all over the place, but this is useful for all kids.
Designed in Fusion 360 with some calipers and a couple food pouches. I had Comforts and Earth Best brand food pouches, but I think they all have a similar neck and size. Message me if you find a brand that doesn't fit.
Print upside down. A brim helps keep it from falling over when it gets to the end but you can get away without one if you have good bed adhesion and maybe print a little slower.
