Budget
As a team building a larger structure, we had to carefully work within our budget constraints to build an immersive box that fulfilled our major goal of polished fabrication. Our largest costs came from wood that we used for the frame, and also from tool rentals to make up for shortcomings in the woodshop tools.
In total it cost $320.79 for the materials for our project, including prototyping. Of this, we paid for $241.64 worth of materials and had $79.15 donated. If you want to make your own box, the bill of materials for the final version comes to $247.13.
