My own rendition of the Master Sword that can be found in Breath of the Wild.

Modeled based on some reference photos and screencaps. It has a bit of a thicker blade because I thought it looked cool and a bit more chunky.

Size:

The sword is in it's full size just under 60cm. Due to the size the files a broken up into multiple parts. In the files you'll find an unsliced model as well to reslice to your liking or print at a smaller size or even a keychain. 

Weight:

Due to it's length, the sword has a decent weight. I personally stitched all the parts together with the wedges (in the files) and some epoxy. This holds great, but keep in mind that with the wedges it's 100% a decorative piece. If you plan to swing around with it and have some sick Hyrulian battles, please adjust the model to accept some steel rods for a lot more sturdiness.

Finish:

For the finish I personally went for a weathered and rusted look. Like it's has been exposed to rain and dirt for a good 100 years. Feel free to go for the clean purple/blue-ish hilt and clean metal blade. 

Print Settings:

This sword was printed in PLA. I can't remember the exact amount of infill, but everwhere between 20-40% should be well enough.

I've labeled the filenames for easy assembly when printed. Make sure to print the wedge file 8x. The cross should be printed 2x.
