Rounded bridge test

This bridge test model was created to calibrate lid printing performance for the modular container system.It is specifically tuned for:Bridge Flow Ratio: 1.6Bridge Speed: 10 mm/sFilament: SUNLU PLA+The test includes two circle sizes:53 mm95 mmImportant NotesWith 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 uniformBut they slightly sagThis can cause small imperfections or tiny holes in the top layer when printed without supportFor 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.RecommendationI 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 speedFine-tune coolingReduce bridge flow slightlyOr add minimal internal s
