(Late update but still)
Finished the prototype of the LED lit blade! Also functioned as a test for transparent PLA filament.

 - Found that light was too bright on each individual LED when I wanted light to be more dispersed. So! I thought to wrap the inside of the print with parchment paper to help diffuse the light better. Not perfect but looks a lot nicer

Picture attached (right side is with parchment paper and left is no parchment paper)
