Summary These are 4 fun coasters made with a random voronoi pattern. They are different from each other, as a different 'seed' was used for the random pattern on each one. Diameter: 100 mm Height: 4 mm Print Settings Rafts: No Supports: No Resolution: 0.3 - 0.4 mm Infill: 100% Notes: I have printed these successfully on ABS. Because of the holes in the geomery, the surface area isn't too big, and therefore not too prone to warping. I'm sure it will work well on PLA or Flex. How I Designed This They were made in Rhino with Grasshopper plug-in. PM me for details on how to generate these kind of shape. ;)
