This is an accessory for PrintCentral's Raspberry Pi camera case. Should snap snugly onto it.
I needed this because I kept getting flares and glares in my video when the light was not behind the camera. This lens hood gives you much more flexibility with light setup.
Print upside down from what is shown in the STL file
I printed in ABS (235-228 C, heatbed 90) for the flexibility, but it should work in PLA as well.
The walls are 3 to 1.6mm in thickness, I suggest using 3 perimeters to avoid the small infill pattern.
For ABS, print slow, to give the layers some time to cool. If you use a fan, do so sparingly. First print with fan at 15-30% resulted in some layers detaching due to excessive shrink.
