Fender Washer for Flying Crank Ghost

I am a home haunter -- one of those crazy people that go overboard decorating for Halloween in the same way other people do for Christmas. We go to great lengths to build elaborate DIY static props and animatronics. Now that I have a 3d printer, I'm looking for ways to use it for my haunt as I ramp up my construction.

One of the traditional animatronic props is the Flying Crank Ghost (FCG), a slowly bobbing and wafting ethereal figure that works similar to a marionette. We ultimately elected to build an Axworthy (a different animated prop) last year, so I didn't have time or funds to finish my FCG, but I did get started and I'm now revisiting the project. One of the things I learned a year ago was that trying to drill holes in the metal fender washer (the revolving part that the marionette's strings are attached to) was an exercise in frustration when you only have a hand drill and not much work space. It has occurred to me that it'd be much simpler to just print the part with the holes already present.

This part has obviously not yet been tested in an actual FCG, but I don't foresee any issues.

See Kick the Fog or the original design on Phantasmechanics for instructions on making your own Flying Crank Ghost.

Note: Various other parts -- like the rotating arm, the rope clamp, the carabiners (http://www.thingiverse.com/search?q=carabiner&sa=), and the pulleys (http://www.thingiverse.com/thing:25279) or some eye bolts -- may also make good candidates for printing if sufficiently well-engineered.
