Ever since I've gotten sick last year from Covid, my lungs get irritated very easily from frying food and 3D printing PLA. There's plenty of DIY enclosures out there, but I don't have the time and live hundreds of miles from the nearest IKEA. So yes it works, it was easy to piece together, looks pretty cool, and it vents the irritants away so I can use my Prusa again.
Enclosures are well made with easy to follow directions. I bought primary to reduce fume exposure from printing and this enclosure plus the addition of ducting and fans has prevented any noticeable fumes.
