A cube in a cube, at least twenty times.
Just one of my first try with Structure Synth to do a "printable & not so un-interesting" object. Nothing too smart though...
I Hope you'll enjoy once printed.
To be fairly honest : I'm new to 3D printing, my CR-10 should arrive within a week.
If one of you guys is the first one to print it, and shows it's printable before I get the machine: I owe you a beer.
(Thingiverse dates acting as a judge, and pictures of the print being mandatory).
I promise you'll have it.
EDIT : Too late. I owe myself a beer. Cool.
EDIT2 : Ooops : somebody already had the great idea (before me)...
