The metal supports from an old children's bed have bent over time, so I quickly decided to make these. They have worked very well, they are hard enough to support a good amount of weight.

I recommend printing in PETG-FC, and with a minimum infill of 50%. I used 4x25mm wood screws, 5x25mm I think they will also work.

The model is my first 3D design, so it can be greatly improved, but it is practical and if it is useful to someone, I am already satisfied with that!
