The 3D print shape was design to take advantage of the K2 Plus bed size for large one piece object creation. Both parts can be printed on a single bed plate. You may try to resize if it you want a smaller size. The shape was made specifically for candy-floss decoration creations, but can probably be used on cookie dough, clay like pottery or else.  

The way the shape is used is placing a generous handful of cotton candy into the 3D-printed rocket cavity on a clean tray or table. Use the press with the handle to press down firmly and evenly, add more floss and repeat until the cavity is fully compacted and holds the rocket shape. Lift the press, remove the molded cotton-candy rocket, and finish or layer as desired for display.

Recommended to use food-safe PLA to print this.
