Cooling shroud for X carriage drive motor

My X axis motor on my Folger Tech 2020 got hotter than any of the others so I wanted to add a fan to it but couldn't find anything that suited me. I started with 123D and then used Tinkercad after that. It is just a tight slip fit but stays put.

I was paging through things for Folger Tech tonight and discovered that someone else has a very similar design! http://www.thingiverse.com/thing:1001858

Great minds think alike!
