This is a 2 Circle Roller, a geometrical object that behaves like an Oloid. Put it on the floor, nudge it carefully and watch it roll through your room!
You can also have a look at my other Things, I have uploaded five more 2 Circle Rollers there.
I'm a student who found his fascination for 3D Printing when our school got a 3D Printer. Furthermore I'm interested in modeling things with a CAD software. Have fun while browsing through my things!
If you have special wishes for things I could design, please let me know! :D
