If you use one of the many filament clips that attach to Bambu spools, and want to use the spools on an Ender 3 (or other bed-slinger) printer, then this little adapter may be of use to you.

I did not expect that the clip I have been using would have caused a problem as they work really well in my AMS. I came to check on a print on my Ender 3 only to find that the filament had jammed under the clip (which I didn't think could happen). The Ender 3 tried to keep printing with the filament as tight as a guitar string (obviously the print failed).

My solution, make a simple removable adapter to clip onto the top rail of the bed-slinger. It can be positioned anywhere on the top rail and is simple to remove. I have decided to use it for my non-Bambu spools as well.

Works well printed in PLA Basic.
