mbot grid II fan duct

I wanted a better design for my printer. It took awhile, but here it is. It is for a single extruder grid II printer. I did have to wrap the mount with electrical tape for a great fit. The tape also reduces vibration. Google or Amazon B00MJU6JR2 for the fan used. Simply grind off the nub that gets in the way and push it in the duct. You will see when you get the fan. Big improvements for me. Feel free to make it better.

Update: The fan is too loud...
