You would definitely have to get the host sent to a machinist. Mrcrouse, flaminpyro are always up for custom work. They would machine you an extended heatsink to accept the module. Then all you need to do is buy a diode driver combo from DTR and solder the two leads on the driver to the two leads on the contact board and there you go. That would be the easiest way to get it going. But if its not commonly used there is usually a reason. Size, heatskinking, small battery all pose problems.if you wanted a 445 you would need a boost driver so the driver diode combo ould not be an option. So you would need to just get a module and solder on your own driver in place of a contact board. And then you would be running a substantial amount of power from a very small battery. In this build a 638 nm or a 405 nm would be better because you can get the single battery driver pre wired from dtr. Another thing to remember ( if that wasnt enough) is that if you run into any problems, no one will have first hand experience with the host to help you, so other then asking for help from afar, you will have to essentially " figure it out" lol see where I'm getting with this lol. If your just starting, build something that has been built many times and is tried and true. Something like this may be cool because its unique, but would be better suited for you a little later when your " figure it out" skills, are a little more refined. But if your confident ,,,,,go for it man!!
