This is to print a minecraft like pixel sword with a front and back. You will print both sides (which are the same) and glue them together. This gives it a little more thickness, plus it looks cool to have both the front and back have that pixelated look.
there are small SLIM TREE supports at the bottom of the sword, where the hilt is. Those 2 squares are not as thick in order to fit together with the handle of the sword, they need very little support but they do need it.
remove the supports, ensure fit and glue the sword to each handle for each side before gluing both sides of the sword together.
