This is first version of my greatsword series. The picture did not show its real length, it should be around 940mm when it's been printed.

It also should be printed in PLA+ or other stronge layer adheresion PLA material because it's weight more than other collapsing sword.

PETG are recommanded as it has better layer adheresion, but the separating piece should be PLA.

And the XY-hole compensation should be tuned. The middle of the blade are too close if your PETG fillament inflating.

As you can see the fillament has been modified to reduce the cooling. 70 means the max speed of fan will be limited at 70%. It means to strengthen layer adheresion, so please test your fillament first to find out a better parameter. To myself, it can go down to 50% maximum and 10% minimum.
