If you have a DSLR with a non-stock lens, it’s quite likely you have a lens hood to cut down on unwanted light rays. If you have a GoPro, however, it’s extremely unlikely that you have one. If this is the case (and you have access to a 3D printer), don’t settle for washed-out images, just print one of these for your Hero 3+ from this file on Thingiverse!
As this GoPro lens hood seems to be designed with aerial vehicles in mind, it’s optimized for weight savings. It doesn’t really offer much protection for the lens, but if you break the hood, at least you can crank out another one!
If you don’t have a 3D printer, the “XYZprinting Da Vinci” model is available for well under $500 on Amazon as of this writing. I don’t have one yet, or really know anything about that brand or model, but at that price point, I’m kind of tempted to get one.
Thanks, @MetalDesigner on Twitter for bringing this up way back in July!
