Drastically reduce the side to side wiggle of the extruder idler arm/lever that holds the filament against the gear on your Anycubic Kobra. 

You'll only need to remove the top screw of the fan, no other major disassembly required.

You'll need to replace that screw with a slightly longer bolt but it holds tightly in place and doesn't push on the lever/arm, just sits right up against it, limiting the wobble it has. This piece can also rotate so you can get a preferred placement higher or lower on the arm. 

Don't over-tighten as it might bow out the arm. I'll work on a sturdier design that fits the shroud. Or you can use the thicker version without the shroud.

The shroud still (barely) fits if you want to cover it up again.

Print as oriented for the most strength, .2 layer height or greater works nicely. 100% infill cuz why not? PETG is best. A brim can be helpful if you have adhesion issues. One side is slightly flattened for printing. You could also stand it up on the larger end but layers risk snapping more that way.
