About this 3D model

first attempt at 3d printed gasmask inspired by #direngeziparki make shift masks. Using paper towels inside pet bottle. Create small holes in the bottom of the pet bottle and soak paper towels with vinegar and water for better results. This is a work in progress I'm incorporating a one way valve as well as extending it to cover the nose as well. UPDATE: I tested this with some heavy duty mace pepper spray combination yesterday. The results were notthat fantastic. Most of the pepper spray being oily as it is was able through seep through the sides. I Though the mace had almost no effect. Pepper spray is a skin irritant so any exposed flesh will begin to burn instantly. Thus unless you have full face protection you will get effected!
