Some time ago I downloaded a similar box here. Unfortunately, I can no longer find it. I developed a configurable box for other sizes because at the end this model gave me the idea to.

We use these boxes in different sizes for a variety of very different purposes:

• My grandsons use this on pallets with a forklift
• As a magazine for small parts on the desk, but also in the bathroom

I subsequently developed a matching lid for this as well.

Everything is configurable via OpenScad: plank height and width, width of the gaps, number of planks on the bottom and side, size of the box. 

And the box is very stable.

If the box is not too large you can print it without support (depending on your printer). How do you include minimal support you can see in MyKiste_Support.3mf.
