Narrative:

During climb out from mia; passing 11;000 ft.; 280 kts.; a refrigerator sized object passed below right side of fuselage; maybe 10-20 ft. Below. No significant velocity vector perpendicular to our flight path. Object had no wings or foils and was blue and silver. No observed propellers or thrust devices. Could have been some sort of shaped balloon but did not appear to be; as it seemed to have angular geometry. Very high to be a drone and had no likeness to any drone I have ever seen.
