In the short run, you can stick it in an Aixiz mount, hook up the flex-mod, and then stick the Aixiz mount in one of
Pat's micro-mounts. Believe it or not, I've got exactly this configuration in my 1 watt blue Q-beam beam rail, and it works great. (Put a small fan on it to keep it cool, and you'll be golden.)
A nicer solution would be to use one of the many diode block mounts that folks are selling here on PL. I'm rather partial to the awesome solid-brass mounts that Dave and Adrian (Lasershowparts.com) make, but they don't seem to have any on their website at the moment. Also, Johan (Edison) may have a couple designs that might work for you.
DrLava sells a dual-diode combiner kit that is quite nice, if you fancy building something a little bigger, but you'd want a second diode for that. It will be a little more expensive too.
