The photo has an older version I printed. I think this version of the model is better, but I haven't prioritized re-printing yet.
The author remixed this model.
The original included a ball mount, which allowed the stand to be used in multiple positions. I've found this ball mount to be unreliable and I didn't need the flexibility in mounting positions. This version just has a fixed foot, that holds the sensor at 90 degrees, on a table/shelf/etc.
