Hobbing fixture for mill

thingiverse

Using a 2 mm end mill or a .070" alternative ensures an optimal fit in filing teeth for filament drive, offering a superior "bite" compared to hobbing with a tap. This method also guarantees the drive's roundness and concentricity with the shaft. The fixture allows for precise spacing of 24 teeth. For best results, set the z-height at approximately 20 degrees above the centerline of the shaft; however, a steeper angle up to 45 degrees may be employed.
