Small model of the shardblade Firestorm from the Stormlight Archive by Brandon Sanderson. The sword is modeled on the image drawn in Book 2.

Print two copies of the main blade and one connector, and glue the blade together, using the connector to line them up. The holder is optional and can be used to hang the sword off the side of a Prusa MK3 printer.

[Edit 29/06/2023]: I've added two new files: "Full Blade" and "Blade Full Thicker". The first one is the original model, unoptimised for 3D printing - the blade edges are thin, and it is a single piece with no connector slot. However, this could be useful for anyone making a derivative. The second one is the same but the edges are a bit thicker - this makes it less sharp, so maybe better for printing but less good for models.
