Summary

Tiny Lincoln heads with which to make a necklace. Thanks to Bryan (Thingiverse user bvac) and Veronica for the inspiration.

Instructions

Slice.
Print lots.

I sliced these using a custom MakerBot Slicer profile -- zipped and available for download -- using .1mm layer height, slightly increased resolution, and other things I've probably forgotten. I tried them out in PLA on both an original Replicator and a Replicator 2, and the Rep 2 gave me much better detail. I also tried printing a bunch on a plate at once, but stringing was a bit of a problem.
