Cowboys extruder knob for Ender 3
thingiverse
His is a Dallas Cowboys extruder knob for the Ender 3/Ender 3 Pro. There is a spot where a set screw hole can be drilled out to the size of a set screw that you choose to use. I used a 1/8" set screw. UPDATE 6/27/2021 Added special gcode files for printing it in color on a stock ender 3 series printer. To print in color, Load the white filament. Print the 01 file. When it is done, the nozzle is moved to the parking position and the bed remains heated. Heat up the nozzle to 200 and change to the blue filament. UPDATE 6/30/2021: Added an extruder knob with an extended length shaft. Print the 02 file. You can even start printing the 01 file, go to bed, and change the filament and print the 02 file when you get up.
