Dr Brown's Bottle Cap

Dr. Brown's 4oz Natural Flow Glass Baby Bottle Replacement Cap This 3D-printed replacement cap is designed to fit Dr. Brown’s 4oz Natural Flow glass baby bottles, as shown in the reference images. I modeled this after misplacing some of mine and wanted a reliable substitute. If you need a cap for a different bottle size, let me know—I can adjust the design and upload a new version to fit your needs. Hope this helps!
