A stepper motor wire winder. Great for creating electromagnet coils, and other cool stuff. In the future it would be cool to have some sort of a guiding arm to do precision spaced coils, and a wire cut off/coil slide off/new coil start mechanism. But this should get people who know how a proper wire wrapping machine should work to start thinking. Print 4 pieces, assemble the base with some glue or acetone. Wire stepper up to a stepper controller. Can use ReplicatorG manual controls, or someone with some programming experience could make some neeto code with coil counters, spacing, etc...
