This is a Steam Deck accessory that snaps over the vent to redirect warm air toward cold fingers.  Also great for playing while cozy under blankets.

Tested and it works!

Print with PETG or better, the plastic will get hot during use.

Versions:

• v0.3 Turning vanes.  Fit is a little loose on my OLED model, holds fine during play, bumps off easily.  Not quite the snap on accessory I wanted.
