Concentric spinny thing

Description

I just felt like throwing together something that would be impossible to manufacture with traditional injection molding. I'm sure someone else has done something like this before but I'm just messing around with this new toy.

Sliced with Miracle Grue on Makerware w/ 0.12 mm layers, 10% fill. 2 shells, scaled up to 130%. Printed on Replicator 1. Top surface has a few voids. Should probably make shells =3 and increase infill some.

 Which slicer? I haven't had any trouble using Skeinforge 50.

Yes. The outer two rings print perfectly, the inner two have no top or bottom, and no fill. Just the walls. The pins hold the third ring together, and the center just falls out - so it still works (and REALLY welll) but I haven't figured out why it does what it does yet...

Instructions

Prints fine on Makerbot Replicator Dual with 10% infill, although there's a bit more grip than I'd like between the layers.

For some reason, the two inner rings printed hollow on my T-O-M, but I was amazed by the way the rings moved so smoothly as soon as I took it out.

 Hollow as in no infill, or something else?  I'm still learning how to use my Replicator myself, so I can't really help with that, but yeah I wasn't expecting the joints to work so well.

 Yeah, I thought that was the technical term for it but I didn't want to look stupider than I already did for calling it a "concentric spinny thing." :)
