About this 3D model

Print with the large flat surface on the bed. Use an opaque filament to block the rather bright LEDs. White filament blends in better with the Winix, but does allow light through (see third photo). If you just want to soften the light a bit this may be the way to go. The part will stay in place on its own and can be slid to the left to access the controls. This simple shape and may fit other models, but I haven't tried.
