Specifically, the differences between the original and the final CAD model included the changing of the interface between the adjusters and the adjustable components. Permanently threaded interfaces replaced the threaded claws of the original design. These changes lead to a redesign of the rails and plates and the need for a better interface between the screws and the movable parts.

The pin and carrier assemblies were then developed allowing for a single point of connection and disconnection, and a more stable platform from which to make adjustments.

While these improvements did require additional mounting points, they were generally located on exterior surfaces, allowing for a more robust design, and easier machining.

Additionally, the size of the rails had to enlarged to accommodate the increased size of the chosen micrometer screws.

These improvements eliminated the concerns generated about the aligning of interior and exterior threads. This implementation of a commercially available alternative to cutting our own screws increases the reliability and reduces the machinability concerns of the design.
