So your oversized drill chuck does not hold a 1 mm drill?
Print this collet chuck to hold it firmly. 

When using, align the drill chuck's 3 clamps to the collet chuck's 3 shallow grooves.

... and do not let the drill become hot! If it gets hot (PLA: more than about 60 degrees Celsius), then the 3D-printed collet chuck may melt to the drill and the drill may even become off-centered and break. Therefore this collet chuck is suitable for very lightweight work only, else use a cylindrical metal collet or a smaller drill chuck. Greasing or oiling the drill's tip may help to some degree.
