OP should talk to https://twitter.com/adereth (see: http://adereth.github.io/blog/2014/04/09/3d-printing-with-cl...) and have pure fun together.
Thanks for the mention! For anyone interested, all the source and models for the Dactyl keyboard are available here: https://github.com/adereth/dactyl-keyboard
There's also a talk I gave a Clojure/conj about it here: https://www.youtube.com/watch?v=uk3A41U0iO4
