Eye Wash Bottle for safety and emergency

thingiverse

I wanted to make some experiments in chemistry. For safety: wear protective goggles. Have water to wash immediately when accident happened. Print this, add a hose (8mm outer diameter). Clean carefully all plastic pieces. There is no benefit when water moves plastic particles into your eye. Cut a piece of bicycle tube (sealing ring). Prepare water: Boil 0.5 liter, cool it, add 4g salt (NaCl), mix carefully. Have clean bottle. Life time of this water is 3 days. Have it all clean. If you have injuries in your eye, a bacteria soup is not a benefit. Different bottles will have different thread. I have made the design for 2 bottles. Brown plastic bottles are better. Glass bottles are not good, because you need to squeeze them. threads.scad is a copy from here:https://www.thingiverse.com/thing:1938150
