I am definitely interested. And yeah I also think the number of actual atreus users also into moding is probably quite low compared to some other boards. Not that it matters really since everything is open source.
I love your design btw, as I said on reddit I am in the process of building a new board based on it with some modifications. I think I might try to get a transparent acrylic "middle layer" to fill the gaps once I am done. In any case I will let you know and post pictures here.
Thanks again for the hours you put into this, it's really superb.
