The d3wey "Frame'ish" is my take on GoPro's version. It uses the same prinicpal. The nylon material is elastic enough to fit tightly without warping. It really is a perfect fit.
This weighs just 4 grams and allows access to all buttons. It was made for use on my DJI Phantom but can be used for many other uses and is a LOT cheaper than having to buy the genuine item.
In this current revision the camera can now fit either way giving access to the shutter button in either orientation (so you don't have to fiddle with up/down settings). There is a stronger bracket and small cut outs to allow large Mini USB plugs to fit.
*** - Please Note - *** As with any Shapeways product please be aware of what you are buying. This is a custom designed part not mass produced. It has a slighty rough finish (but nothing that will scratch items). I make every effort to test all my designs but I regret manufacturers do change their products from time to time. If in doubt please contact me.
