Requires the pin connectors library http://www.thingiverse.com/thing:10288 When I was making that, I thought it would be cool to turn it into a chain, so I made this quick script to make customizable flexible bracelets or necklaces. Tell it the diameter you want the chain to wrap around and how many linkage sections to use and it'll make a custom sized plate of parts and tell you how many times to print that plate to get the length you need. Alternatively you can print the individual parts in different colors.

Also might work as a bike chain style cable...

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...
