Fun Ender 3 (Bowden extruder) Extruder Knobs

Description

I've seen a number of extruder knob designs. I wanted to add my own personality to my printer and these have been great. They print very quickly and can be functional if desired. For me, they are decorations. R2D2 actually looks like a little droid printing a part, complete with sound effects. Noisy printers finally have a purpose!
