Looking really good. How comfortable do you find the left thumb cluster? I've been eyeing that layout for my next build. You don't see too many DM with a full bottom row like that, interesting, what did you use to to make that happen?
The left thumb is pretty similar to the Kinesis Advantage which I've used for years. No issues with comfort there!
The layout is a 5x6 full matrix. Wylderbuilds has the option to print with it, but I think the software used to generate the model supports it as well.
