This is a remix of the original knob I published, https://makerworld.com/en/models/1955210-rv-stove-knob#profileId-2101278

This version has the position markings configured as a modifier so you can change the colors to suit your needs. This was printed with Black and White PLA. No supports are required. Print face down. I used 6 wall loops to increase the strength of the shaft. These knobs have been in use daily for over a month without any issues.
