This is one of those DIY projects I should have done a long time ago. I solder a fair bit and mostly use lead-free solder, but sometimes there are those projects where you need to use the bad stuff. I cringe each time I do it and pop the gas mask on and bear through it. I finally decided to do something about it . 10 minutes of DIY hacking and I have a fume extractor. Given I already had the fan, this cost me a few bucks to make.
