Diffuser for Olympus FL-LM3 flash

thingiverse

The diffuser is a simple slip-on design that fits snugly onto the movable head of the Olympus FL-LM3 flash unit, which comes standard with cameras like the OM-D E-M5 Mark II. Its design is based on a model found at https://www.thingiverse.com/thing:3060393 by snapwithdale. However, when I tried using this original diffuser, its thickness caused a noticeable reduction in flash intensity, and my E-M5 II was unable to compensate. After chatting with the designer through comments, I measured their product carefully and recreated it as closely as possible using Fusion360. I printed this revised diffuser in "vase mode" to minimize its thickness while maintaining its structural integrity. When standing upright with the closed end on the print bed, it is remarkably thin yet surprisingly durable – it has survived several trips in my camera bag without sustaining any damage. Despite not having used it extensively, I am eager to hear how it performs for those who decide to print this design.
