This week's selection is Spiralis by Shapeways designer Emm@nuel. There are actually two variations of Spiralis in the Shapeways catalog, the Spiralis+0,025-7cm and the Spiralis+0,025, which appear to differ only in size.
Designer Emm@nuel describes Spiralis as:
Mathematical oddity composed with 20 triskelions (triskelion, triskele) and 12 spirals.
You can request a 3D print of the Spiralis from Shapeways in a variety of materials and colors, ranging in price from USD$58 (white plastic) to USD$267 (Gold plated).
