Lightsabers In Only One Command!

In spirit of the new Star Wars movie coming out soon, I decided to make lightsabers in only one command. Every lightsaber is different and has cool buffs. There are 6 different lightsabers, Blue, Red, Green, Yellow, Purple, and Black. Crafting is below.

To add the machine to your world type in 3 commands before it, I will make a second command with these but for now here you go.

/gamerule commandBlockOutput false
/scoreboard objectives add item dummy
/scoreboard objectives add crystal dummy

The World Download is the command!

Crafting
Blue: Diamond + nether star = Permafrost Crystal
Green: Emerald + nether star = Sage Green Crystal
Red: Redstone Dust + nether star = Scarlet Crystal
Yellow: Glowstone Dust + nether star = Impact Crystal
Purple: Purple Dye + nether star = Amethyst Crystal
Black: Ender pearl + nether star = Black Crystal

Light Sabers: Drop one of the crystals with a stick to get a light saber of the crystals colour.

The Schematic is the arena I made as a little extra to test out the light sbaers with other people, Lightsaber PvP anyone?
