This video shows an enclosure I built for the Xtool D1 10 watt diode laser
This isn't a tutorial, but if you are building or looking to acquire an enclosure, this might be a source of ideas.
Edit: I just noticed that I said the fire extinguisher activates at 170 degrees Fahrenheit… I should have said Celsius.
I will post resources here soon.
