Imperial Cog Fan Grill

Show your dedication to the Impire by covering your fans with my eye-balled version of the cog!

My basic story is that I had a different 40mm fan guard that worked fine until I moved my fan location and found out my fan's fins stick out just above the top edge of the frame. Meaning I needed a new fan grill that slightly raised off the frame so it wouldn't rub the fan fins. In doing so I thought I'd make a couple other variations as well.
