Nice, but antenna patterns are typically shown on a log scale. It would probably be better if he'd 3d printed on a linear scale, which would give a better physical idea of what the antenna is doing.

Most antenna patterns are plotted at the 3dB roll off. While this is logarithmic, it's also "half power".
