Samsung burner knob DG64-00473A fits popular gas ranges like the NX58H5600SS and NX58J7750SS, and it is one of the most-replaced knobs on any brand — the metal-look coating and the D-bore both fail. Print a tougher PETG version in the color you actually want. Note: Samsung ELECTRIC ranges (e.g. NE63 series) use a different stem shape — measure yours if you have an electric model.
Shaft fit: D-shaft, ~6mm class (community-measured 6–6.75mm; printed replacements verified on NX58 models). Original knob is 2-3/8″ dia — confirm your stem before ordering. Knobulator lets you set the exact bore
shape and clearance, so the knob grips the shaft instead of spinning — the usual failure of
one-size-fits-all replacements.
