A toy box for my bath toys. It fits under my kitchen helper:
I built this a while ago. It's not perfect, specifically, the ends aren't restricted enough to stay upright, so I wish I would have made two hooks from the sides into the ends, but with a friction fit, it works well.
After 6 months of use, it turns out the bottoms are warping a bit, due to standing water, but I took it apart, and flipped them so they cup down and it hasn't gotten worse since then.
Let me know if you make one, please!
I ended up trying a new technique for this build. The boards are s4s pine, and they are too thick (for my taste, and for the notches I cut), so instead I cut them all out first, and then I ran them all through my thickness planer until they fit well in the slots.
You need 2x of each part.
