Quick rundown, this is a 3d printed PAPR system for 40mm NATO gas masks. It takes 20v DeWalt batteries but I have plans for other brands in the future. I also have plans to be able to use other brands/ threads for other filters.
Jumping off my last post, several people were interested in beta testing the project. I’ve started a discord for the project where anyone is free to see updates, offer recommendations/fixes and most importantly find the files & build list.
Keep in mind this is just an open beta for now. I would not use this for anything too caustic at this time, but it should work fine against dust. I do not have a fully fleshed out build manual or wiring diagram yet (although it’s fairly simple even without one) and I expect to make many more improvements in the future. Thanks for the support!
