3D Printing

General Notes

• Use 3MF files if possible because they're far smaller than STL
• Set Z to 0.1 mm before leveling with regular printer paper. Then you get the correct distance.

Design Considerations

Modularity:

// - Expands the 26x26 table to 256x256 to encrypt ASCII text
// - Uses the Beaufort cipher's method of symmetric encryption/decryption using the table
// - Uses the Autokey cipher's method of expanding the encryption key with the plaintext
// - Base64 encodes the resulting ASCII ciphertext for easier display

const beaufortAutokey = (key) => {
  const ascii = () => Array.from({ length: 256 }, (_, i) => String.fromCharCode(i)).join('');
  const shift = (text) => text.length <= 1 ? text : text.slice(1) + text[0];
  const rotate = (text, distance) => Array(distance).fill().reduce(result => shift(result), text);
  const base64Encode = (text) => btoa(text);
