Powered Air Purifying Resperator Air Pack
thingiverse
This is a 3D printable Powered Air Purifying Respirator, air supply. Everything except the filters and electronics are printed from PLA, but for a final unit I may switch too ABS. It uses inexpensive RC parts, about 70$ (with 25$ 2-4 hr battery). Any questions are best asked on my youtube channel, as I don't spend much time here. More details in the youtube description. https://youtu.be/w3eHPeeaxNA
