BTT Octopus Stepper Driver Fan Duct for 40mm Fan

I originally used the stepper driver fan duct by mbrady6 but the 5015 made the entire back panel resonate. This remix solves the problem by allowing a 40mm fan to be used to cool the stepper drivers. Simply bolt the two pieces together and then bolt on your favorite 40mm fan. I am using a standard BB 40mm fan and there is almost no noise.
