Thank you Dexter.
Follow same print directions as file that this is a remix of. Prints nicely.

My stove is a Whirlpool Super Capacity 465

I measured the stem/shaft that knob fits onto on my stove, at it measured 8.5mm in diameter, and the filed side was 5.9mm.
Also, different than the original thing, my stove apparently has the shaft 90 degrees rotated.

So I have two files, one with same shaft orientation as original thing and one rotated.
