Led ring support for Ø50

I have made a led ring support Ø50, inspired from retaining ring for E3D v6: http://www.thingiverse.com/thing:671250

This is modified to customize this led ring with OD60 and ID53 which I bought from here: http://www.aliexpress.com/item/2-pcs-set-Universal-Use-6000K-Diameter-60mm-COB-LED-Angel-Eye-Halo-Ring-Retrofit/1763106374.html
