I've attached a pic of the host I received. I've ordered a complete laser module with driver from DTR which should be arriving soon. As far as I know, it should be an easy install as all I gotta do is drop the module into the heatsink and throw in an 18650 battery. But upon looking at the silver ring part (driver pill?), it's hollow and I'm not sure how the battery is going to push up against it? I believe I did order "drilled driver pill" but I thought that meant it had 2 small holes I could use if for a different driver in future purposes.
