Fan Mount for Voodoo 3 2000 (and other 40mm heatsinks)

There are two versions – one with one side blocked off, intended to face the AGP slot on the Voodoo 3 (since any air going “down” is blocked by the slot anyway).  I've also made a version with a less restrictive bottom for other applications.  The heatsink on the Voodoo 3 is approximately 7mm tall, so this should clip on to any heatsink that is 40x40x7.  Due to the extreme heat of the Voodoo 3, this needs to be printed from ABS or other heat-resistant plastic.  Screw holes sized for m3 screws, but you can easily adjust to taste.  To ensure the clips don't have any support/bridging artifacts, please print upright with supports as shown.
