These 0.2mm high, 2D sine waves based on https://www.thingiverse.com/thing:11243 are for testing bed leveling and adhesion. Since the printhead is always changing direction during the sinusoidal motion, poor adhesion will show up quickly as straight lines between where the filament tacks to the bed.
This is a quick print that's fun to watch.
If you have a good caliper (0.01mm resolution), you can measure the trace height and width of the sine waves and compare them to what your slicer is expecting. For instance, if you're slicing just doing a single, bottom layer at 0.2mm X 0.42mm, is it really 0.20mm X 0.42mm? It will be taller and thinner, or shorter and wider if your bed Z isn't dialed in properly. It will have the correct height and be either narrower or wider if your E-steps is off.
