3. Match each part to the correct filament color.

• PLA filament

• Layer height: 0.2 mm

• Infill: 10%

• No supports

Print flat on the build plate.

2. Slice the file.

3. Preview the colors.

4. Start the print.

Troubleshooting

• Everything is one color:

  • Open the original 3MF file, not an STL.

• Colors are wrong:

  • Reassign the parts to the correct filament.

• Sign will not stick:

  • Clean the build plate or add a brim.

• Text is too small:

  • Make the sign larger or choose a thicker font.
