It’s a cool idea. but, it would be sturdier if you used wood glue before clamping. I might use wood glue and 1/4” screws to make it the sturdiest.(via WHORANGE: turn IKEA into I-CANDY: pränt box modular shelving)
This is pretty, but I’m concerned about its structural integrity. Don’t put a fancy vase on top of this if you end up making it.
