A mold, comprising:
- an inner body that includes:
- a first pair of side walls, each of the side walls having first and second sides that extend for a length;
- a pair of engagement members, each of the engagement members extending for the length of the side walls attached to one of the side walls by at least one hinge;
- a second pair of side walls;

A mold, comprising:
- a first pair of side walls, each of the first pair of side walls having a pair of engagement members attached thereto, each of the engagement members having sides formed at a first angle, the first angle being one of acute and obtuse;
- wherein each of the first pair of side walls and each of the first pair of engagement members extend for a length;
- a second pair of side walls extending for the length, each of the second pair of side walls having sides formed at a second angle complementary to the first angle such that the second angle is acute if the first angle is obtuse, and obtuse if the first angle is acute;
- and
- a separation mechanism in contact with each of the second pair of side walls to the extent of the length;
- wherein each of the engagement members engages and secures one of the second pair of side walls in part based on sides of the first pair of side walls abutting sides of the second pair of side walls according to the first angle and the second angle.
