DIY 3D printed PAPR blower

thingiverse

Still a work in progress, but feel free to take what works and run with it so that usable products can reach the people who need them. I need to refine the wheel and scale back down to 2" or so to get maximum rpm out of the small motor. A 12V RC hobby or drill motor would likely work well with this sized blower. Anything that works well becomes scarce, but I hope anyone who can print a fidget spinner can also print a working PAPR system. This design uses: 1 608 bearing 1 5v DC motor 1 filter media of your choice - applying power makes less breathable filtration media more useful 1 clear document cover for the faceshield 1 yard of homewrap tyvek or similar material to construct a hood The long neck with a hole was intended for wearing under a hood, but testing with the dinosaur costume blower showed mounting on top of the head is less bothersome. Ideally, the finished system should not require a belt pack and hose because I'm having trouble finding a good sized nice flexible hose locally right now.
