 you can download them at

 but it'll go down if too many try it at once. 
 i was basically trying to get some nice, unique lightsabers that weren't overpowered (which is hard considering all the cool effects you can put on these puppies). 
 oh, and they're not upgradeable, like i said, i just did these because i was bored, so they're pretty lazy.
