50 X 20mm Spinner Knob (Flatted Shaft - Experimental)

thingiverse

Had trouble putting vertical triangular knurling pattern on knobs in Fusion360 so I cheated it. I took a fine toothed gear drawing, created a scalable vector graphic (.svg) file out of it and imported that into F360. Extruded the sketch to make the knob outline and added the rest of the features normally. Easier than trying to understand the super fast video on the "tube". Should be printed with the spinner hole side to the build plate for best looking print or the shaft hole will get messed up by the printer if it doesn't print overhangs well. (Mine does but many do not). This is really still a work in progress, and may be edited further in the future. Can be printed using whatever material you are comfortable with. Adjust the diameter slightly in your slicer (while keeping the Z axis separate) if the shaft hole comes out too small or too large on your printer. My printer is a Creality CR10 V2 (not in the selections so used CR-10S). I've included the Fusion360 .f3d file and also a FreeCad .step file for those who don't have F360 so you can edit & customize this to your own liking.
