I thought the red on my aluminum extruder was reminiscent of Iron Man so I thought an arc reactor extruder knob would look good. So I took the arc reactor design from tollychandler https://www.thingiverse.com/thing:685177 and put a stem on it to fit the Ender 3 extruder. It's my first time really editing and designing so let me know if it works for you!
