⚙ 3D Printing Recommendations
First layer height: 0.20 mm

Subsequent layer height: 0.15 mm

Material: PETG

Additional Tips
Use a heated bed (around 70–80 °C) for better adhesion.

Nozzle temperature is usually in the range of 230–250 °C for PETG.

Recommended print speed: 40–60 mm/s to avoid stringing and ensure accuracy.

For PETG, it’s helpful to enable low fan speed (20–40%) so parts don’t overheat but layers still bond well.
