I could not make this, but I would surely love to buy it.
I was in that period before sleep that is the most creative. Thinking of a goal, having a solution, beating that solution up to find what is wrong with it, and changing the result, beating that solution up etc. At one point thinking of making the suggestion that Glowforge design in a place to hook up a CO2 bottle and a delivery system to use even on small flames that only a tiny amount of CO2 would be necessary to fill the entire chamber and douse any sort of fire ( @dan this is still a good suggestion to think about for the future designs!)
But of course, for those of us with a Glowforge Pro such a designed in concept is too late as we have no access point…Oh yeah, there is the pass-through slots with the removable shields! I notice that many folk who are using them are only using the front slot but we don’t want to eliminate the possibility of using the rear slot occasionally.
However, if there were a removable rear shield, that would still operate as a shield, but contain the capability to let in a cloud of CO2 via a 1/8 inch slot that would dead end and thus still act as a shield not much more CO2 than needed to fizz a bottle of soda would put out almost any fire and so could almost be a first solution even over a wet rag. With a car door opener as a means, you could be across the room and give it a touch and instantly have no more fire, Using the equipment already available to fizz soda bottles the expense of using it need not be great. Unless you were silly enough to try cutting magnesium in which case you would deserve to lose the Glowforge, I can see only a single slight problem of cold shock and only the company engineers could make that call.
How about it? Does anyone wish to pile on and say what a bad ides this is?
