Another extruder feeder knob.

I liked the chunky feel of https://www.thingiverse.com/thing:3325902 so much I decided I'd also want it on my feeder assembly,

Print out "Extruder_Feed_Knob_Just_The_Tip.stl" as a test piece before printing the main knob, if it fits nice and snug you are good to go.

If it's too tight/small either lower your flow rate, or scale it up by a few %

If it's too loose/big either up your flow rate, or scale it down by a few %

once you have the settings that provide a nice snug fit, load '
Extruder_Feed_Knob.stl' change the settings to match and print.

Rotate it by 180 so the stem of the knob is facing up,

Printed in PLA at 0.2 Layer height, no supports needed.
