Remove Venturi Tube Thermador PCS366US

Brand:Thermador
Model Number:PCS366US
Main Symptom:Venturi Tube Tool Needed
What happens & when:

Need to know what tool to remove venturi tube. Tube is not connected to the “star” part of burner, just sits inside.

I don’t know if it is stuck yet, just not sure on how to remove. Will update with pics ASAP

The venturi tube can be removed with a 20mm socket if the beveled edge of the socket is grinded to where it is flat and there is not a bevel inside of it.
