Separate Shield - Toolhead Development

As discussed before, it’s a good idea to make the hotend shield and the brace two separate parts. We'll make the bottom of the main body completely flat flush with the Beacon mounting surface. This will improve printability and lessen the potential warping. The faces with the most extreme overhangs (inside the ducts) will be moved to this separate shield part, which can be printed in a more suitable orientation. This split will also make nozzle changes with silicone socks easier.

The pic of the old vs new (WIP, no duct cutouts yet) is below.
