Sigma EM-140 ring flash holder

A common regret when photograph work with a macro ring flash is that the image seem flat. This is due to the lack of shadow caused by the fact that the light come from the point of view: the same effect appear you use a headlamp by night.

This tool permit to hold the flash in a better position. It have 3 easy freedom degrees :
* the angle of the camera fixation,
* the angle between the two threaded rod and
* the angle of fixation of the flash.

Note that I add 2 grips from [MaxGlide](http://www.thingiverse.com/thing:84142).

There is many way to mount it, you can remove the photo screw for tripod holding (I add this to take a picture for Thingiverse) or add an over handle. Its parenthood with [TV support for camcorder](http://www.thingiverse.com/thing:1096886) give you even more possibility.
