I don't like to throw all of my utensils into one big container, so I've designed this internal divider for the Ikea ORDNING utensils holder.
It's designed to snap into place (the upper part has a lip that grips the edge). There's also a "peg" at the bottom that goes into the center hole and prevents any movement.
This was designed for the smaller Ordning holder which is 13cm tall. It should be held firmly in place once you snap it in, but I've noticed that some containers are slightly oversized, which might not create a tight fit.
No supports needed, print with the circle touching the bed.
