Smooth Wall Grain Bin Candy Dispenser

This is a Smooth Wall Grain Bin designed for Skittles, M&M's, and other candies one in or less in diameter! One cap screws onto the bottom and the other goes into the hole on the top. I have not printed a prototype yet and I'm not sure if it works. I will eventually get it to work but for the meantime please comment what can be fixed.Boost MeBoosting me allows me to make more better models and will allow me to get a 3D printer! If you download and you are satisfied, a boost would be extremely appreciated :D
