I knew that Printrbot was supposed to be "Open Source" and with some Googling, I was led to this site:
I didn't scroll through all 250+ entries there, but maybe you can find what you are looking for.
You might also try GitHub; I know I found some Printrbot Plus design files there once upon a time. I didn't immediately see them today, but GitHub is notoriously fussy about how you Search; it seems like it finds every excuse NOT to locate what you want to find...
Good luck.
