Here are pics of my prototype candy drop box. I will use it until after the build is finished when time allows making a better looking one. After building the original height of the box, I decided to relocate one fuse cross brace and then was able to make the box taller. Hence, you can see the added section at the top. The internal measurements are 3 1/2" wide X 7 1/2" long X 6" high. Also, there will be a cover hatch on top to preclude anything spilling out and into the fuse prior to release.
