Modified Rawolr's Master Sword files from thingiverse to turn it into the one from the Tears of the Kingdom trailer, most files are the exact same as the non-metal rod version of the original, only changes are Blade_1, Blade_2 and Blade_3 are replaced by Blade_tip; and Blade_4 is replaced by Blade_mid. Blade_base is the exact same file as Blade_5 on the original, just renamed to avoid confusion.
As this is based on the non-metal rod version of the sword, i wouldn't recommend trying to hit stuff with it, it's mostly designed as a display/cosplay prop piece.
Left and Right guard pieces can be printed as a single piece or as halves to avoid supports, handle has two versions, with and without the “cloth” wrapping around it.
To reiterate, most of the files weren't made by myself, credit for the original sword goes to Rawolr on Thingiverse.
The author remixed this model.
