Antifog antifog system for x800 or similar glasses

Version of the well-known exfog system to eliminate fogging of ventilated goggles, for airsoft, sky or other sports where fogging of eye protection is a problem. The box and lid are quite simple because I prefer the versatility of being able to assemble the system both with new materials, and with recycled components from other products, and that anyone can edit the stl as best suits their needs. A heat glue gun is required for assembly, in order to seal possible air leaks that would affect the flow inside the tubes. In case of using new components, I recommend the following: 5V 5015 type fans. The case is intended to be able to attach 2 of 5 cm. 1 18650 rechargeable battery 1 18650 battery charging plate 1 switch 6mm flexible tube inside. Another possibility, which was the origin of the project, is to reuse components. As a fan I used one from an old laptop that works at 5v, and as a battery/charging plate I used the one from an old powerbank. I have left the internal structure of the box smooth, precisely looking for that versatility that everyone can assemble it as you want with the components you can find, either new or recycled. The connections are very simple, connect the battery to the charging circuit, + with + and - with -. That done, we connect to the same negative contact of the charging board the negative of the fan directly. The positive contact of the fan, we connect it first to one of the pins of the switch and the other pin of the switch, to the positive of the charging plate, thus being able to turn on or off the fan and being able to charge it when we want. The 6mm flexible tubes attach to both outputs of the connector and go directly to the inside of the goggles, being able to pass them through the rubber of the goggles. It would be convenient to drill a few holes in the frame of the goggles. The assembly: First we make the connections and make sure that the fan-battery system is working properly. Using the heat glue gun, we attach the fan, and through the large window of the case, we seal the gap left between the fan and the case. Then we attach the other components, battery, charging plate and switch. These 2 through the holes provided in the case. We seal also the cover with thermal glue, always seeking to avoid possible air leaks. Finally, we slide the connector along the guides of the box and when it is centered, we seal it again with some thermal glue. With a 18650 battery, it has lasted me on without shutting down about 24h, so the autonomy is total. Of course it can be charged by another powerbank, or in the car through a microusb or usb type C connector depending on the charging plate that you have put. It only remains to drill 2 holes with a drill to the glasses and pass the tubes. I recommend passing the tubes through the bottom of the goggles to promote the upward flow of hot air. The box can be attached to a helmet or cap, using Velcro.
