Useless®

Today i was bored, roaming in the house with me frickin' broken arm.
So i decided to create something like my afternoon: useless. But is it? Could be possibly everything: a shelf, a cupholder, a flowerbox, a book holder, a stool, a bookend!
Try and print, use your fantasy and make it become what you want. I'm too curious to see the results.
The scale is medium small (140 x 140 x 210mm), scale, cut and do whatever you want.
It's Useless®!
