Needed both in the game and on the server
Pre-cast Structure lets you build once, then reuse that work anywhere.
Frame a volume with platform floors, perimeter fencing, and a scaffold for height. Scan the interior into a Blueprint, feed it into a Structure Printer with the required materials, and print a portable Pre-cast Structure item. Hold it for a hologram preview, then place it where you need another copy without having to rebuild it by hand.

Compatibilities:
- Create: Supported
- Sable/Aeronautics: Supported
