The Skyzone SKY02S V+ 3D is a nice pair of goggles but it suffers from the problem of fogging as soon as I put it on. While most solutions aim to replace the face-plate, I like the original face-plate and want to keep it. So I created an add-on with 2 U-shaped ducts which bend around the face-plate to extract moisture from the eyes.

The mount is designed for 25mm fan. I use a 12V one from eBay and drive it directly from a 3S battery's balance plug.

Print with a brim if adhesion is a problem.

Print the ducts on their side, and the fan mount upright.

Depending on how well your printer performs on printing bridges, you may need to trim the inside of the fan mount a bit to fit the ducts. Use some glue to make it a bit air-tight (not 100% necessary).

Mount the fan so that it blows and sucks the air out.

You will need to peel off the cushioning of face-plate a bit to mount the assembly, then stick it back. The 2 vents should sit right above the eyes.
