Here is a good Halloween Prank! Put a laser proximity sensor facing out of the hole, a small battery, a party popper explosion piece, and a bright LED inside, put a piece of paper on top, and wait for someone to walk by! Will require you to try out some things, but priceless if made correctly! Do note-you will have to scale this yourself based on the components you are putting inside and the printer you are using. Have fun, like if you enjoyed, and comment your successes! #TrickOrTreat3D
