Widemouth Fan Duct for Rostock Max Part Cooling

This is a fan duct for Rostock Max that directs but doesn't overly restrict airflow from a 30mm fan. I went a little crazy making iterations to arrive at this design, using each one to print the next. This is the last one, and it works the best.

Update 2/18/15 - The UNTESTED version has a radius to prevent dragging on the bottom edge... I found it hit my print bed's binder clips sometimes when doing big prints.... I'll be printing one shortly to replace the one I've trimmed down, so probably go with that one if you're going to print this.

I'm using this on the version Rostock Max v1, but I think it would probably fit the v2 as well.
