This bridge test model was created to calibrate lid printing performance for the modular container system.

It is specifically tuned for:

• Bridge Flow Ratio: 1.6
• Bridge Speed: 10 mm/s
• Filament: SUNLU PLA+

The test includes two circle sizes:

• 53 mm
• 95 mm

Important Notes

With the settings above, bridging performance is excellent the bridge lines come out clean, consistent, and well-defined.

However:

• At Flow 1.6, the bridge strands look strong and uniform
• But they slightly sag
• This can cause small imperfections or tiny holes in the top layer when printed without support

For the 95 mm version, I added small internal supports because the top surface was not forming perfectly without assistance — even though the bridge itself looked very good.

Recommendation

I strongly recommend printing this test model before printing the final containers and lids.

Depending on your printer and cooling performance, you may need to:

• Slightly adjust bridge speed
• Fine-tune cooling
• Reduce bridge flow slightly
• Or add minimal internal supports for larger diameters
