3D plot of complex sine wave

thingiverse

3 dimensional plot of the function Z = Im(sin(x + iy)), allows one to clearly see how the hyperbolic sine is related to the regular sine. Printing upright gives the smoothest surface, but is more likely to sag or warp during printing. To create a mathematically correct representation, the stl-file was generated by a python script using the numpy-stl module (https://pypi.org/project/numpy-stl/)
