LG Studio Replacement knob

My sisters LG Studio range knob broke so I built this from taking measurements from another knob's part, unfortunately I don't have an exact model number to share at this time.  I recommend using the 3mf file as there are some negative components that adjust the height of the cylinders on the bottom to make it fit within the LG studio range knob. I tried running a Boolean mesh to make it all one piece, but apparently there is an internal intersection somewhere that is preventing me from using Bambu Studio to run the mesh and I am just not savvy enough in 3D design to figure it out elsewhere.  If I do manage to fix it I will upload the model.  On the stl file, if you add negative cylinders to remove the center piece sticking up and then another to reduce the height of the tube for the screw to the height of the original center cylinder you should end up with something that fits well.
