Macro rig "Mark II"

This is the 2nd version of my macro rig for Canon S100 and 50mm FD lens (http://www.thingiverse.com/thing:1185765).

Since the lens adapter, the camera base and the led ring are all separated pieces, the concept can be fit to any camera or lens by using different adapters.

The final assembly is compact and solid enough to be carried everywhere.

LED ring resistors are designed for a 3.6V supply, allowing use of a single 18650 cell or 3 AA NiMh cells in serie to power the system.

LEDs used are stadard 10mm white LEDs with the tip filed.
