So, doing some DIY for my Elinchrom Ranger Quadra.
First, hard plastic protection cap for transporting.
Next, and this isn't done yet, but a little sneak peak, is the speedring. This is all Aluminum, other than the bolt/screws, so it's actually quite light. I still need to dremel out the notch for the large retaining knob, and shave off most of the screw heads in the inside diameter. I really didn't like the design of the default Elinchrom adaptor, it does not keep the entire bulb inside a softbox, so I created mine to do that. The problem is that leaves no room for screw heads, so I have to shave them almost completely off.
