LED Flash Ring diffuser for macro photography - Reflex Canon EOS - 67mm diameter

thingiverse

This is a flash ring designed specifically for my Canon EOS 60D camera lens.\r\nI made it to accommodate a 67mm diameter optic.\r\n\r\nTo create this flash ring, I utilized pieces of 12v LED strips, which proved to be an excellent choice.\r\nThe interior surface of the ring is lined with aluminum foil for enhanced reflectivity.\r\nThe outer casing is crafted from translucent gaussian plexiglass, alternatively you can print a thin layer of white PLA plastic.\r\n\r\nTo power the 12v LED lights, I considered several options:\r\n- Building a battery pack using eight AA batteries (1.5v * 8 = 12v)\r\n- Employing a power bank with a voltage regulator to transform its output from 5v to 12v\r\n- Utilizing a 9v battery with a potentiometer to convert it into 12v\r\n\r\nI ultimately selected the third option, utilizing a 9v battery and potentiometer, due to their compact size and lightweight.\r\nTo house these components, I designed a custom box that fits snugly onto the camera's flash slider.\r\nThe result is seamless operation!\r\n\r\n-------------------------------------------------------------------------------------------------------\r\n\r\nUPDATE: For those interested, I have uploaded the flash slider box STL file to Thingiverse at https://www.thingiverse.com/thing:3956521
