The filleted part (except for the impossible edge)

The picture on the right shows the finished part in the state it will be before machining (except for the one edge that is impossible to fillet). You will notice that one edge that runs around the whole part has been left unfilleted on purpose. This is the edge where the bottom and the top of the mould meet. Here, no fillet is possible (and none is required anyway).
