3D Printable Petri Dishes – Clear PETG Set

This project features a set of containers inspired by classic Petri dishes, designed specifically for 3D printing. They are made from transparent PETG, allowing for a clean, glass-like appearance when printed with the right settings.

🔬 Features

Material: transparent PETG
Design: shallow dishes with matching lids
Shape: cylindrical
Height: approximately 15 mm, matching the proportions of standard Petri dishes

📏 Available Sizes

40 mm
50 mm
80 mm
100 mm

Thanks to their low profile, these dishes closely resemble traditional Petri dishes and are ideal for organizing small parts, displaying samples, or educational use.

🧪 Printing Tips (for best transparency)

To achieve the clearest possible PETG finish:

Print mode: vase mode (spiralize outer contour)
Bottom layers: 5
Line width: 0.8 mm
Nozzle: 0.4 mm (works without issues)
Print speed: low (very important for clarity)

Additional recommendations:

Use stable, slightly higher PETG temperatures
Minimize retractions to avoid artifacts
Ensure proper flow calibration

💡 Summary

This design focuses on simplicity and realism, closely mimicking traditional Petri dishes. With proper print settings, you can achieve a very clean, almost glass-like result. These dishes are useful for hobby, workshop, and educational purposes.

A great project if you want to push the visual quality of transparent PETG prints
