I had recently gotten a new camera and housing but am waiting to purchase a strobe later. While I like the PT-15 housing, it is a little awkward to hold on to and I wanted some form of handle. I also wanted to wait until I was ready to purchase the strobe before inverting in a tray so here is my solution to the problem. This DIY tray is simple, cheap and I justed tested it out on a week long trip to Bonaire. It's not too pretty but it does a nice job for the $10 or so I have in it. The "tray" part is a 7 1/2 x 1 1/4 x 1/4 inch piece of scrap lexan, all of the other parts are SS, aluminum or brass purchased at a local Lowes. The thunb screw and weight are the ones that come with the PT-15.
