This is a simple Brontosaurus boarding platform designed for convenient travel and customization. Due to the location where I chose to build, the foundation would not snap at the required height on the upper-left triangular section of the platform. To work around this, I used quarter walls and a triangular ceiling piece to achieve the correct alignment.
The overall design is intentionally kept simple, providing a solid foundation that can easily be expanded or modified to suit your own preferences and travel needs.
