This sword is from World of Warcraft and is known as The Devouring Cold One.
I highly recommend using custom supports, but I am still test printing this with different support styles to figure out which has the best results.
Note: The pictured print was printed with no supports!
I also recommend scaling this model up to the size of your build plate to achieve maximum detail.
PLA works well.
I'm very new to the 3D printing and 3D modeling world, so leave me a like and try this print out to support further uploads.
The author marked this model as their own original creation.
