This is a test print for the collapsing swords and Light Sabers. If you can print thing without the rings sticking together then you should be able to successfully print the full sword.

The test print is a total of 24mm high so I change retraction settings every 8mm. Then I compare the changes until I achieve the best result.

Each printer is going to be different but in my case I used a negative “extra restart” distance to reduce the size of the layer seam. Retraction distance/speed, wipe, coast, temperature, speed may also have an effect.
