This is a blade for the Collapsing Lightsaber (Removable Blade) by 3DPRINTINGWORLD. The segments are separated from each other to help aid in the printing in case your printer can't handle the clearances. This will allow the blade to extend and not stick together.
Sorry I don't have a better picture, the models I have printed were broken due to abuse.
Sanding
You may need to file or sand the pieces down to get a clean fit.
