I picked a fairly weathered Vader 2010 removeable blade saber up and am missing the plastic blade emitter. Does anyone know where I could get a replacement one? I saw one for sale on shapeways as a 3D printed one. I would just need a thumbscrew to lock it on. Also does anyone know how to tKe apart those removeable blades? I seem to need to fix 1 or 2 LEDs where there is black spots.
