I ordered this from shapeways and was disappointed to find that the rolling ball, rolling gears, and rocker switch were stuck in place and not functional. I used a knife to cut into the edges of these pieces while pushing on them and got the rolling gears to be fully functional and the rocker switch to sort of move slightly. The rolling ball doesn't work at all. My fingers are all cut up from these attempts. It's pretty cool overall but I wouldn't really recommend this unless you're willing to do what I did or you want a nearly completely silent fidget cube-like device.
