Cooling Cover for Samsung Gear VR (Note 4)

youmagine

I printed this design in PLA with 15% honeycomb infill, using a two-dimensional pattern to maximize air flow. I secured the fan with two 3mm screws and nuts, taking advantage of the nut traps built into the fan itself. To attach the battery pack, I used a sturdy rubber band from a bunch of fresh kale I had purchased at the supermarket - a bonus is that kale is indeed good for you! This cooling solution works more effectively when the phone's back cover is removed, of course. With the added weight of the battery pack, it's highly likely that users will want to employ the over-the-top-of-the-head strap with this alternative cooling cover in place. The OpenSCAD file does contain some adjustable parameters that can be tweaked for meaningful results, although its fundamental geometry and dimensions are not fully parametric. Experimenting with the design is recommended. A second version of the design has been added, featuring improved centering and support for the battery pack, as well as a block to prevent the fan from blowing directly onto the user's face.
