Escher Fish #20

pinshape

Here's a 3D-printable model inspired by the iconic "No. 20 Fish" design of M.C.Escher, found at mcescher.com/gallery/symmetry/no-20-fish/. This model is quite challenging to print accurately enough to create multiple objects that tessellate perfectly, often requiring some sanding or carving to make them fit together seamlessly. The bottom surface features a chamfered design to prevent any excess material from the first layer from interfering with the outline of the object. To facilitate easier assembly, I've reduced the outline by 0.25mm.
