Here's my version of the Jedi Battlelord's Lightsaber from SWTOR. Just print out the three parts(or the full thing if your printer is tall enough) and glue them together, you might need to sand the connection points to get them to fit. If you want the crystal to be transparent just print it in translucent filament and tint it blue or print it in clear resin.
Be sure to post a make and check out my other models.
