Earth Extruder Knob

Added the D-Shaft on this model of Earth and scaled it to fit an extruder knob.

In Cura, you may have to rotate the part, simply select the part, click rotate, and click the “align face to build plate” button, and click the flat spot on the bottom of the model.

Printed on an Ender 3 V2 Neo with these settings:

eSun metalic PLA+

Bed: 60C

Hotend: 215C

0.1mm layer height

50mm/s print speed

Supports: Tree supports (I found this was unnecessary with the stock cooling of my printer)

Infill: 15%

Buildplate adhesion: Brim (10mm)

This is a relatively high tolerance part, if you are unsure of the accuracy of your printer, print the first centimeter and see if it will fit. If it is too tight, scale the model up a percent or two.
