Airsoft safety goggles anti fogging fan

thingiverse

Fan duct for airsoft safety goggles for a fast helmet, to prevent fogging. I used the following parts: Switch, cable and fan cover https://www.amazon.de/gp/product/B07F1NV9T7 Silent fan https://www.amazon.de/gp/product/B071W6JZV8 Battery case (3x1.5V): https://www.amazon.de/gp/product/B094W9XJWV Goggles https://eu.novritsch.com/product/antifog-safety-goggles-large/ Helmet https://eu.novritsch.com/product/tactical-helmet/ Helmet adapter for the switch https://www.taiwangun.com/tactical-helmet/adapter-kit-for-accessories-to-helmet-with-rails-black-fma Pouch for the battery case https://www.taiwangun.com/pouches-leg-rigs/rear-counterweight-accessory-pouch-for-fast-helmets-multicam-em M3 screws, length unknown Use the template part to mark exact holes on the helmet. To do so, cut out some pices from the helmets NVG mount and insert the template part instead of the fan, mark the necessary holes. For the large hole, use a hole saw. Add an additional hole for the cable, but be aware that the NVG mount covers the hole later. Use the seal part between the helmet and the fan. Glue the switch on the helmet adapter. Create holes using a revolving punch plier on the upper and lower side of the goggle. Good success Odo
