This collapsible sword is made to be printed as one part and not requiring you to re-calibrate your printer. I tried printing some other collapsible blades and even with my printer tuned I still had issues with it. It drove me crazy enough for me to create my own with thicker tubes and spacing. This way you can print it successfully without messing with your E-Steps, Flow rates, speed etc. I also created it to be printed at .2 resolution. So a full sword can be printed in 12 hours at 60mm/sec, instead of 2 days.
