Any thought of updating this to use the new pins.scad you created?

Yeah I should... the vertically printed pins on this break so easily.  :)

I'll keep my eyes out for the update then.  :)

Check out this cool roller chain sculpture thing that I'm sure you could print using this http://www.youtube.com/watch?v=Tcw7IvGJG9shttp://www.youtube.com/watch?v... My bracelet totally moves just like that. :)

Very cool. Could be easily modified to make the bracelet wider, by making the pins longer and having some short pieces with holes on each end. I'll have a go at it.

And then a bike-style chain could be used instead of a toothed belt to drive the X or Y stage of a RepRap, reducing the number of vitamins needed. We'd need a sprocket design too. I really need to get my extruder working again....

Parametric sprocket

so, it is currently a high backlash belt replacement?

I don't know how accurate or strong you could make a printed chain/sprocket driven reprap, but I've heard drive chains are being used in diy cnc machines with great success, see: http://www.youtube.com/watch?v=x-tDJAon3Aghttp://www.youtube.com/watch?v...
