Knob for the lid of a (Creuset) pot

The knob from a lid of a Le Creuset pot broke. Here is a new one.
I inserted a M6 nut in the knob. The M6 nut is 10mm between the flat sides of the hexagon and 5mm thick. There is 1mm room.
The trick is to pause the print when the cavity for the nut is complete.
have a look in your slicer and search the layer where the hexagon converts in a circle. It's just before the circle starts that you have to insert the following commands :

G91 ; relative positioning
G1 Z20 ; raise nozzle 20 mm can
