This design uses two colors, printed together. I designed it to fuse together, so it is not fragile. It was inspired by my own drawings.  The base should be printed separately, and is optional. I printed the black and white fish with ABS filament, .2mm layers. 40% infill. I designed this using Autodesk 360 and sliced it with Simplify3D, then printed with my Qidi Tech 1 3D dual printer.  For best results, be precise when aligning the black and white sections for printing.
