This is an extremely spooky and very dangerous ghost floating across a window. Approach with caution! ;-)
This model is to be fixed to the two sides of a window with double sided tape to make it appear like it's floating through it. I used a slightly transparent white PETG filament to print this model.
The author remixed this model.
I stretched the model vertically, split it and added some tabs for double sided tape. It's meant to sandwich a window to make it seem like the ghost is floating through it.
