A little sign I made to let kids know that we have candy on Halloween. I live in an apartment where all of the porch lights are always on, so I had to come up with another way of flagging down trick-or-treaters.
The size was determined the printer I originally made this on, a 3D Systems Cube 2. Feel free to scale it up and play with it.
If you can't print it yourself, check out my store on Shapeways.
