So here is my challenge, is there anyone here with the time/ability/interest to build and create the how-to write up?
I would do it, but with no work bench or way to put things to the side and come back to them I feel very limited.
Oh come on. You don't need a work bench to do this stuff. It's PVC pipe. It's one of the easiest construction materials in existence to work with. A hack saw or pipe cutter and maybe a ruler is all you need. Eyeball the length, cut, stick it together, done.
That pvc contraption is way too much effort and thinking anyway for what you're asking.
How's this for a 10 minute project solution if you have a table surface to set the helmet on which is where the helmet is probably sitting right now anyway:
2 pieces of 2x2 (or equivalent size spacer which can be nearly anything laying around) cut to support the helmet up off the surface.
2 pieces of 2x2 about the size of the computer fan. Screw the fan onto the wood with the flow direction up. (An inch clearance off the surface instead of two inches is more than adequate)
Side note: Computer fans are 12V mostly. Electronic junk shops have 120VAC versions of the same thing that's the same size with a much higher air flow. Get one of those. They're typically $2-$10. They're the computer size fans that are used in the big electronic racks not computers themselves.
Put the fan in the middle of the bottom between the helmet support 2x2's and set the helmet down on the whole thing.
Open the visor and plug the fan in for an hour.
Done.
Don't leaving it running forever. Too much air dries all the foam out completely which is not good for it.
If you're really clever, you can build the supports and fan base as one piece though that's the advanced high tech version that requires either glue or a couple extra screws and about two extra minutes to build. If you have a soldering iron, you can put a switch on the thing.
