The Ghostfire Dagger from the Roblox Marketplace, or Two Time's Dagger from Forsaken if you know it from there.

Notes:
The files are not designed to be printed right away. I was too lazy and stupid to redo the files so that they look normal in a slicer. Make sure to reorient both parts to be standing upright and scale both up. I personally used a 888.56% scale, and it turned out great.
supports for the blade piece, no supports for the handle. the support in the little hole piece in the bottom of the blade came out fine, so no worries about that.
basically just print both parts in different colors, then add a drop of superglue in the hole and stick the handle in.
(i sharpied on the spawn logo in the photo btw just for that extra touch)
