Me too, when reading "open source" I was expecting some design docs or the like. Aside from the general confusion of the website, I haven't been able to find some of the most important information. For example, there's no diagram or immediate explanation of the general working principle and airflow path. The heat exchanger itself is published only as-is for those designs, while the author writes that he uses a custom python script tuned for the design size and his 3d printer to generate it.

When i saw this I immediately thought of studying it and reuse some of its designs for my custom use case, which does not appear to be currently possible.

At first glance it appears to be "open source" in the sense that you can buy it, but if and when something breaks you can print/reorder it easily.

Correct me if i'm wrong
