4 cones were printed using the stl file in the project files. the cones were printed with the top of the cone facing the bed in order to reduce the amount of supports required and make sure structure is maintained. once printed the cones can be connected together by filing down the pins until they are short enough to be pushed into the holes in the above cone. A 3mm screw can be used to screw into the end of the pin to stop the cones disconnecting.
