Spreading my current project pollution here rather than in the what did I buy... thread.
MK II Fume extractor, smaller, stronger, simpler design, less parts and laser cut a filter sample which works great. Also split the rear fan cover to get better material use/sheet (jigsaw feature
).
Any thoughts on what would a flatpack kit with everything (including hardware) bar the 120mm fan be worth delivered to your door? Postage with 4-6 filters is just on $7 USD anywhere on the planet.
I'm the original cheap bastahd, and I'd buy that kit without thinking twice if I saw it at Fry's or MicroCenter in the $10-12 range. The more filters, the quicker I'd snatch it up.

IME, that means normal, more "consumer-ey" minded folks would probably go as high as $15, maybe even $20; especially if you remind them that they're saving $40-50 over the HAKKO by DIYing.
The problem you're going to have with those sorts is... you'll have to write up a short treatise on fan selection. Sure as shootin', even in THIS relatively well-educated market on eevBlog, you'll get some yo-yo who puts a low-speed Noctua in there and blames you because it doesn't suck.

A couple suggestions...
1) The center medallion area on the back seems a bit large; at a guess approx 55mm. Looking at my collection of 120mm fans, only one AC-powered unit has a motor that wide; the rest are 40-45mm. Whether it's so or not, that large medallion area APPEARS to block some airflow, and might cost you some potential sales.
2) You could also offer an "Option" of a strip of 12V white LEDs to go on the front inside edge of the hood; that thing will be well positioned to shine light right on the work pretty much any time it is in use.
