50mm Fan Fingersaver

Hate that buzzing noise when you accidentally touch the blades of that super-speedy mag-lev fan? Is the tip of your nose now slightly shorter than yesterday? Do I have a solution for you!

This is a fingersaver for a 50mm fan. Parametric file (solvespace, free oss) included in case your fan is slightly different.

Pros:
* Fingers are not eaten by fan
* Fan blades do not contact heat sink
* All sorts of things stop intersecting the high velocity fan blades

Cons:
* Fingernails no longer
