kit anti-buée pour masque chirurgical

thingiverse

Human: This kit consists of two flat bars measuring 1 mm each, as well as two clips that allow you to pinch the mask between these two bars. It helps block airflow from being exhaled upwards into your mask and glasses, preventing condensation from forming.\r\nYou will find the bar and clip in a single file or by lot of 10.\r\n\r\nFor functionality, the bars must be formed around your face by heating each of the two bars using a hair dryer before applying them to your face. \r\nTo form the bars, heat until they become soft and "droopy".\r\nStart by forming the nose bridge, then the wings, then the cheeks, making sure to apply the bar so that there is no gap between your face and it. Feel free to re-do it several times, as PLA cools quickly.\r\nThe second bar can be formed around the first one. It's also important that the two profiles are well connected, with no gaps for air to pass through.\r\nThis shaping operation takes 10-20 minutes, it is essential to do it correctly otherwise efficiency is compromised.\r\nOnce both bars are ready, pinch the top of your mask (also formed on your face) between the two bars and block it with a clip on each side. \r\nThe entire set is of course reusable. You may need to remake the profile of the bars if they have become deformed for any reason.\r\nFor example, you can find them in blue, but of course the kit is much more discreet printed in transparent or white.
