I made this LED Ring for my SJCAM SJ4000. I made two parts, the outer ring is for a 60mm LED ring ( http://www.amazon.de/gp/product/B010AUNOY8 ). The inner ring is best printed with flexible material. It has a little lid to get some space between the outer ring and the power button. ;) Printer: Da Vinci 1.0a with E3D V6 hotend Rafts: No Supports: No Resolution: 0.2mm Infill: 20% Print the inner ring with flexible material like NinjaFlex or TPE filament.
