## Materials Required
Please refer to pages 30 through 38 in the documentation.
Some materials are required while others are optional.
Some materials are contingent upon a lack of access to other materials.
Some materials are potentially concerning purchases for those in legally precarious circumstances.

## Print Settings
Please refer to pages 39 through 55 in the documentation for specifics.
You know your 3D printer better than we do, so unless you are new to 3D printing, your intuition takes precedence.

## Build Instructions
Please refer to pages 56 through 103 of the documentation.
