Escher Fish #20

thingiverse

Here's a 3D-printable model inspired by "another" M.C.Escher fish and based on http://www.mcescher.com/gallery/symmetry/no-20-fish/. This project was challenging to print accurately enough to tessellate multiple objects - many of mine needed some sanding or carving to make them fit. The bottom surface is chamfered so that any excess on the first layer won't interfere with the outline. I've shrunk the outline by 0.25mm to make it easier to fit together. If you want to adapt this (reduce the tolerance from 0.25mm?) or see how it's done, get the model from OnShape.com - search Public documents for "Escher Fish". Print Settings: Printer Brand: Printrbot Printer: Simple Black Rafts: No Supports: It Doesn't Matter Infill: 10% is Fine Notes: Slow speeds are necessary for accurate outlines. Don't over-extrude. Scaling this down in X/Y will make it more difficult to print.
