Countdown the last 25 days before Christmas with this ornament. Turn Santa's sleigh to spin the planetary gear system, in turn spinning the snowflakes.
This ornament is meant to be printed on a high end FDM printer with soluble support or an SLS printer. Our prototype was printed with a Stratasys Dimension SST 768.
