Bike light mount, with quick release

Update 14.01.2017
If you are using softer materials are not powerful enough for quick release and ability to pop up.
I uploaded a 0.5mm and 1mm increased a hingedistance version. This results in a stronger locking, but it increases the possibility of breaking clamp.
The correct size may be selected experimentally. I PLA and PET-G is the event of the basic size work.
It results in failure of the locking even if the actual clamp inside diameter is smaller than the captured light. This problem is more scaling should be improved.

I bored with the lack of a normal quality of light, the normal price.
So I took a cheap but good Chinese LED lamp and was planning to add a powerful and convenient mounting bracket.
