Thanks for sharing. I really like the "reusable" din rail clip of this thing series. The Raspberry Pi mount however, has an issue. At least with my settings of the slicer (Cura). The four mounting rings were very brittle and broke off.Maybe a simple round design (instead of the one side being flattened) would be printed more reliably? It was one of my earlier prints, though. And even if the mounting rings broke away, it was still perfectly possible to mount the Pi with the remaining holes in the support frame. I also made a different din rail clip: https://www.thingiverse.com/make:303528 . I like it more because it holds the Pi more tighly as it is attached to the din rail at both sides (and not just once in the center).
The beauty of this design here is the modularity: splitting the mount into the Pi support frame and the din rail clip.
