Looks great. Where did you get the PLA made?
For adding the glow in the dark, do you mean to paint on something at the end of each layer? Seems like that would make the blade very weak, which it already is. Not sure how to solve that problem other than the metal rod inside it, as mentioned.
I should revisit this design, add some snazzy to it. Light on the emblem or maybe a thicker blade with LEDs inside.
