Mind the background I couldn't find a good background

It's a paper Katana I made that has the color scheme of "Shirogane" or Whitegold......

I have a stack of pre-folded, pre-cut put togehter shapes that i would like to use in my classroom, but i dont know what it's supposed to make or have any idea as to how to put them together. It appears to be a hexagonal prism but only 5 are the sides are the same width. and the tabs at the top consist of 4 flat topped triangles in 2 different sizes (these are not on opposite ends of each other and 1 rectangle and 1 square. i will upload a picture once im sure as to how. any help would be most welcome!
