couldn't find a good pop up dispenser for sticky notes (the ones that come zigzag)

So designed this simple dispenser.

At first I left both sides open but since the top part with the opening weren't connected to the bottom it was very loose, so I added the triangles on one side to help with stability and so the sticky notes don't just get pushed through to the other side.

printed this at .28 layer height with the closed off (triangles side) down.
