Box within a box within a box and so on and so forth

I made this on OpenSCAD, and it is basically the same holey rounded box within a holey rounded box five times. I printed it with dissolveable supports, and after scrubbing the glop off of every surface in my kitchen, I was pretty pleased with the result!

With the dissolveable supports and all, it took 13 hours and 45 minutes to print.
