MES Smoke Stack?

What do you use for power on the fan? Aren't they like 5v?

Here's my soup-can variant.

The players....a tin can and the stock damper (the little handle has been lopped off)

I riveted the can onto the remaining vertical flange from the old handle. This serves to hold the can on, but it also allows me to still open/close the damper by twisting the can (I really only close it for critter prevention during storage).

.
We seem to have acquired a slew of AC adapters from old electronics Found one that was appropriate for the fan and spliced it on. Only took a couple of minutes

Yeah, that's mine.  I did away with the vent stack.  Too much draw with the fan at the end of the stack.  By placing the fan next to the vent opening the draw is gentle and by adjusting the distance I can adjust the draw.

Have you ever tried to insert a rheostat or variable resistor.

Very cheep and works for slowing or increasing the speed of the fan.

Thanks for the tip. I did think about it but went low tech. Appreciate the link
