gas mask

thingiverse

Inspired by #direngeziparki's makeshift masks, try a 3D printed gas mask prototype. Use a pet bottle (350ml), fill it with paper towels and create small holes at the bottom. Secure the bottle with two rubber bands and ropes for a face fit; no scaffolding needed. For added protection, soak the paper towels in vinegar and water solution. This project is work-in-progress, incorporating a one-way valve and extending coverage to the nose. Note that recent testing with heavy-duty mace pepper spray had mixed results, as oily pepper spray seeped through sides; full face protection is advised due to the irritant nature of pepper spray on exposed skin!
