I found this thing really useful when I had multiple leftover pieces of wire and didn’t want to use tape to hold them together.

It can hold the wire in place and secure it while rewinding on the AMS, without the need for tape.

It fits perfectly on the official Bambu Lab spool without needing glue, but it can slide to the edge.

I’ve seen some straps that take up an entire spool, but for situations where only a small amount of wire needs to be used up, this is perfect for about 5-10 meters of wire.
