Im making a 3d printer pen and I'm stumped. I can't figure out how to make a small extruder like what lix has
People are wary of the legitimacy of the Lix pen and don't seem to know what the heating element exactly is, you're probably better off looking for something that is already created like the 3Doodler and it's knockoffs

What have you tried and where are you getting hung up?
