Here are two recursive snowflakes, one composed entirely of hexagons, the second of hypocycloids.
The openSCAD code that produced them was supplied to me by D J Moews who kindly allowed me to post it here under the attribution creative commons license.
Both snowflakes have hexagonal symmetry; the hypocycloids having 6 cusps. The two snowflakes are similar but the one composed of hypocycloids is slightly more open. However it takes much longer to calculate.
The snowflakes have sides about 48 mm long and a thickness of 3 mm. They can be printed with or without a raft. Dxf files have been included for the laser engravers.
