Pretty nice looking host. Good luck on your sale. What is the heat sink diameter of this one? I see you added a separate module inside the heat sink. Is it held in place with set screws? Trying to get a good understanding of how well it might transfer heat from the 12 mm module to the outside heat sink.
I'm really sorry for my sloppy photos, I'll give you more details
diameter host is 45mm ,diameter heatsink is 24mm and have screws to fix parts together
