The file '90mm Cupcake/ToM LED Ring 3D Printer Model' is (stl) file type, size is 9.5KB.
This is a derrivitave of http://www.thingiverse.com/thing:7484
but the cheapest on ebay uk i could find was 90mm (£7 for 2 inc shipping from HK) so i made the ring bigger.
I also removed the nasty 90 degree overhang in the clip, and reduced it to a nice 40degree slope.
Sorry but licence is same as the original
