Waveform Surface

This creates a customizable surface where both the x and y axis are an independent waveform. There is an option for a Fourier Transform - like waveform. Start with low smooth (faster render) and change the parameters until you find a surface that you like, then move the smooth higher (slower render) and press the "Create Thing" button.

Note - the square and sawtooth waveforms will not print correctly for high smoothness,
since the vertical drop will be too thin.

Infill - about 30%
Support - this will cause marks on the underside, depending on the surface, you can try without support
