Gear VR - 40mm Cooling Fan Mount (Consumer edition)

This is a light weight alternative to some of the Gear VR fan covers. It will slot into where the white plastic part of the Gear VR meets the black part. You can reposition the mount to change where the air flow is, depending on where your phone's hot spots are. You may need to trim down the legs in order to mount them near the middle, as there is less room near the middle for them to slot in to.

With some testing, I found that a single 40mm 5v fan is more than enough to prevent over heating,
