"Muffin fan" is a tool? (AKA "Pancake fan")
I'd certainly say YES! .
My old much-modified muffin fan has finally quit, so I ordered a muffin fan last week--
Amazon--$12.
Although it's the correct wiring and voltage, the size is smaller than what I thought I was going to receive. (Never good at math, the metric system ruined my "gozintas"

).
I can still use it for it's intended purpose, but in looking for another muffin fan over Memorial Day weekend, I found a lot of ways to get flummoxed.
You can get tiny computer muffin fans for $1, but some vendors require a minimum purchase of 100!
Muffin fans are cheapest in DC current, which means you can run them off a suitable transformer you've saved from some other application; however, connecting the wire connectors might be a hangup.
Regarding connectors, this latest fan came with two spring-clip connectors. Press down on the tiny levers and slide the wires in--release--and you're connected.
Fan blade rotation and breeze-direction are indicated on one side. If you're ducting your fan through PVC pipe and using a single port, send the breeze
out.
Muffin fans also come in house current (115v-120v/220-240v), but not all have the plug!
There are even muffin fans in stainless steel!
But my old muffin fan was a US-made "takeout" (routine replacement) from a
Xerox 2400 "duplicator" machine I was maintaining in 1972!
"Duct fans" have much more power, but are shorter on durability. They're available at
Home Depot stores in sizes 4-inches and up.
If your Sunfish is stored outdoors, look for a
solar-powered muffin fan!
