I was in the market for a softbox and came across a great deal on an Amvona Dynaphos softbox that I couldn’t pass up. The softbox came with a speedring, which was just a flat, circular sheet of metal with a pattern cut out of the middle that allowed Amvona hot-lights to be removed with a quarter turn. Luckily, it was easy to remove and replace with whatever I wanted. I could’ve modified that metal speedring that came with it but it was pretty beefy and would’ve taken longer to cut. To make life easier, I opted for a piece of 3.2mm styrene (plastic) that I got at a local hobby store (it was with the model train accessories). The actual material isn’t important, you could use styrene, ABS, plexiglass, wood, and so on, as long as its fairly thin and sturdy.
