Hi Everyone,
I have been working on a design for a useful motor that can be produced with a RepRap. Latest results are at:

It uses rare earth magnets, 3D printed plastic parts, and a PCB for the coil. I think it would be cool to incorporate the drive circuitry onto the PCB coil board, so you could make a functional motor with one reprapped PCB, and some printed plastic parts (and magnets of course!). That's the next step. Eventually it would be really cool to see printable motors driving printable sarrus linkages like this [

or printable linear rails like this [

Software for generating your own custom coil patterns is available at the thingiverse post above. If there is interest I can put up a tutorial on the reprap wiki for how to adjust the design parameters and make your own coils.
