I'd prefer Clojure source files.
I've also noted one key in thumb cluster getting stuck. To be honest, the thumb cluster on my 4x6 dactyl-manuform is way less user friendly than that on my Kinesis Advantage. I'll be doing a "normal" dactyl next, as this is much closer to a kinesis advantage.
@Symbiote google "makerspace" (or "hackerspace") + "Denmark", and you'll find plenty of places in the larger cities, typically you can 3D print there for free. Also, many city libraries are starting to put 3D printers in their basements and what not, typically free to use, or just pay for filament. I too thought I'd have to pay a bunch to get mine 3D printed, but I'm printing for free now.
