For my mold and casting assignment, I am using a component that 48 of them create a whole sphere.
My intent is making the components together by tighten with a rope that is going through.
By this way I could also flip some components to create different surfaces from the same component.


Since I am using modela to mill the wax and using the tools that we have in the lab. I did some restrictions. I should only have slope to one side (it is because I have 3 pieces) and since the tool that I use for finish milling has a limited milling depth, I have decided to make only rough milling to the parts that may stress the tool since these parts also seems not to make difference to my final casted piece.
(plus I will gain time by this way)

The final mold to cast the component...a photo that is showing the place of the small piece........
 I used wooden sticks and sprey an oily liquid in order to have the holes inside.
Through this holes, a rope is passing through. So when the rope is tighten up, the force is holding the pieces together.
