Escher Fish #20

cults3d

Inspired by a M.C.Escher fish and based on mcescher.com/gallery/symmetry/no-20-fish/, here's a 3D-printable model that's quite challenging to print accurately enough to tessellate multiple objects. Many of mine needed some sanding or carving to make them fit together. The bottom surface is chamfered so excess on the first layer won't interfere with the outline, making it easier to assemble. I've shrunk the outline by 0.25mm for anyone wanting to adapt this design, reduce the tolerance from 0.25mm? To see how it's done, you can get the model from OnShape.com - search Public documents for "Escher Fish".
