3D Printing Recommendations

Material:

• ✅ PETG (recommended)
• ✅ ABS / ASA (if it needs to be more robust & temperature-resistant)
• ⚠️ PLA works, but can become softer with heat / sun

Settings (Guide Value):

• Layer height: 0.2 mm
• Walls/perimeter: 3–4
• Infill: 15–25% (Gyroid/Grid)
• Top/Bottom: 4–5 Layers
• Support: mostly not needed (depending on printer/orientation)
• Brim: optional (for better adhesion)

Assembly & Fit

The nozzle is simply pushed onto the original tube and tightened.
Depending on printer tolerances, the fit may vary slightly:

🔧 Tip:

• If too tight → lightly sand inside / use “elephant’s foot” correction
• If too loose → a piece of tape on the tube or a thin strip of TPU/filament as a “seal” ← This was not necessary for me
