Materials & Assembly:

• Uses a 20×18×600mm carbon fiber tube (available on AliExpress), cut in half.
• No additional hardware required.
• The fit between the carbon tubes and the print is snug, but may vary slightly depending on printer calibration. If it’s loose, you can:
  • Slightly scale down the model,
  • Add a thin layer of tape to the tube, or
  • Secure with a drop of glue.

Note: The top bases are universal—simply rotate them as needed for your chosen configuration
