so, implicitcad takes scad, and generates stl, not the other way arround. :)

Yes, see the log:

$ extopenscad -O things/right.scad 

Merely the link is incorrect (the scad file needs to be generated). I uploaded the file here: https://gist.github.com/hasufell/360c81482d0a1f7a7d49c46b42968fff

ok, looking at that scad file, I can tell you that implicitcad has no color operation, and worse for your model, has no hull operation. determining how to implement hull in a signed distance field is a hard problem.

[julialongtin]

what scad generator are you using?

[hasufell]

It's generated from clojure code: https://github.com/dpapavas/lagrange-keyboard/blob/master/src/lagrange_keyboard/core.clj

It appears to be scad-clj "0.5.4-SNAPSHOT".

Started a dialog with upstream to see if we can fix this integration for you.

[julialongtin]

so, it looks like the library is not the source of the issue, but the decisions of the keyboard's designers.
switching which upstream i bother. :)
