I don't know if Casey distributes it, you may want to ask on the Molly Rocket discord.
If I remember correctly it's based on Ryan Fleury's custom layer, that you can find on github.
Casey also uses custom 4coder build from his own 4coder forked source code - it is not the same as public 4coder release, so his config probably won't work as is.

I think Casey only uses Ryan's custom layer now. There's even a 4coder_fleury_casey.cpp file in the github. There is also a 4coder repository on Casey's github page but it hasn't been updated for a long time (the Ryan one is more recent). In that repository, there's also a theme file that isn't up-to-date, here's the most recent one.

The discord isn't allowed more members afaik. I really want to join but can't :(
