This part facilitates precise calibration of your 3D printer's extruder. By using a sharpie, you can mark the filament at the top, then follow the outlined procedure to adjust the extruder's rotation distance accurately. Here’s how to use it:

Prepare the Extruder:
  - Set the printer to relative positioning mode with G91
  - Heat the extruder to 240°C (or your prefered temperature) using M104 S240 T0

Measure Filament Extrusion:
  - Once the temperature is reached, execute G1 E100 F100 to extrude 100mm of filament.

Calculate New Rotation Distance:
  - Measure the actual extruded filament length.
  - Use the formula:

• Current Rotation Distance / Measured Distance * 100 = New Rotation Distance
• Example: If your current rotation distance is 6.9 and you measure 97.5mm extruded, the new rotation distance would be calculated as 6.9 * 97.5 / 100 = 6.7275
