Chain Spool

thingiverse

Specifically designed for jewelry chains, this spool also accommodates thread, yarn, twine, solder wire, or thin electrical wires. Compatible with Storage Cubes (http://www.thingiverse.com/thing:192896), it features a cut-away similar to a shaft key way for easy spooling. For optimal printing, use 0-5% infill, .25 mm layer height, and 1 inside file with 2 outside files for the best fit. Separate designs reduce print time and eliminate support material.
