We had a 315M. My wife bought a brick-sized block of aluminium, drilled holes in it and screwed the laser on. You need to insulate the aluminium and laser with some heat sink paste. Aluminium is better than steel, since it's easier to drill into. We also made DCG holograms, and our home-made heat sink lasted all day, about 8 hours, with little rise in temperature.
If you want to buy one commercially, you might look at Adafruit (
