This is a wrench that can be used to loosen the connection of the Infinity Feeding bag from the G-tube port when the connection becomes too tight. I've added a ring on the other side that should be wide enough to slip onto the feeding bag stand's bag holder. It prints well in PLA without supports. I hope you find it useful, I created it couple of years ago when I found one's online that seemed a little overpriced. I like mine better as it has some knurling for better grip. I've use it for a while so it seems to be a pretty solid design. If you know someone that has a kid with a feeding tube or a nurse that works in a pediatric unit, print one for them, they will appreciate it.
