I did my best to create Sokka's space sword irl. It's blank so no engraving but I made it myself and after some sanding and special glue keeping the pins in place it should look amazing. I printed the handle (hilt) in white and the blade in black (cause Sokka's sword is black). So I can customise the hilt with paint and engraving. It took me a week and some hardware adjustments but it came out nicely. I recommend not printing to fast to get the best quality.

supports for the top pointy part.
All the blade parts should be printed horizontal. Your printer should be able to print the "sharp" edge without supports

The hilt parts should be printed vertically, as you would hold the sword pointing up.
