Someone had taken the spool from the red filament. As a result, the filament would never get back into a spare spool as the filament spilled out along the sides.

I designed and printed some mandrels. The mandrels have a recess on the back for a 1/4-20 bolt head. The bolt head would have been a way to convert torque from the bolt to the spool. Sadly for me, I did not have any threaded bolts that long, with the 1/4-20 bolt head. I ended up using a 5-1/2" allen headed bolt with washers and two nuts. The two nuts acted like locknuts. I duplicated the mandrels for the new spool and the bad spool.

We used a drill as a motor connected to the new spool. It fit nicely around the end of that 1/4-20 bolt.

We chucked up the badly coiled filament into another spool with its own mandrels. We used coat hangers to hold the mandrel of the bad spool.

We then used a spoon to act as a means of keeping the filament even in the spool but it failed due to the filament cutting the spoon. A gloved hand did a good job afterward.

We had to do this twice as the first time we did it, we used too much tension and caused the new spool to expand outward toward the edges. This prevented the spool from fitting in our Bambu printer.
