Nice!! Looks like you’re building a few there. An army of Friken sharks with laser beams on their heads maybe? Did you turn the current adjust multiple turns? The LED should turn off after about 5 complete rotations (at most)but even if it doesn’t I guess it’s fine so long as the current is below 2 amps . Anything over that will fry the diode after a short period of time . I think that if you sell a kit with fitted connectors and a pre-tuned driver/laser it would definitely be a value for your customers and I’m sure you could design a nice enclosure with built-in eye protection too. Also, did you use the fan connection with a voltage divider or do the firmware mod? Just curious since I didn’t do the voltage divider myself but I’m pretty sure it would work.
