I wouldn't think so. The common filaments used for printing are not great candidates for anything that could get hot. Of course they are molten and deposited in the printing process so it's not hard to imagine that they do not like heat. I had a printed part fold over and collapse in the heat of an automobile in the summer.
My son has a Signals/Billows system and I made an adapter for his to fit his Primo. Of course that is different than the Guru type cylindrical mount.
Your best bet is to have a proper adapter made. A machined tube to fit the KK port welded to small plate which is drilled for sheet metal screws to hold the fan. Here's one that is made for a 3/4" NPT coupling mount and a FireBoard fan just as an idea. BTW, this example is used on a Lone Star Grillz stick burner. Such an adapter could be made then the Billows fan drilled and attached with sheet metal screws. I toyed with such a adapter but since I am a FireBoard and Guru Fan user, I moved on.
EDIT: The follow up post directly below postulated on the printed material that was affected to be PLA - it was ABS. "The Person" doesn't use PLA.
I had similar problem with a fan installation because it was overheating very fast. Actually I still haven't find a solution. I do agree that some adapter might help to prevent the material from heating
