Let's get something together in order to remove some of the Note4's limitations.
For now, let's say the project goals are to:
Improve cooling during GearVR use
Add the ability to charge the battery while the phone is mounted in GearVR
Keep additional weight to a minimum
Proposed parts so far:
3D Printed brass heat-sink - http://www.shapeways.com/materials/brass?li=nav
3D printed plastic inner backplate - http://www.shapeways.com/materials/strong-and-flexible-plastic
Female MicroUSB 2.0 ports - https://www.sparkfun.com/products/12035
Low profile fan: http://goo.gl/SdmHk3
A 3d scan/recreation of the current plastic inner-backplate, suitable for printing modified duplicates
A design for a new plastic inner-backplate that can both accept an ordinary rear phone cover, and a removable heat sink.
A design that would provide power to the phone and fan at the internal battery connector.
