This is a remix of the original Bambu printable spool (bobbin). It will not work with Bambu filaments on cardboard hubs.

I needed more bobbins to rewind from cardboard and non-AMS compatible spools. However, the original needed a separate hub because of the alignment tab and the lack of holes to thread the filament into to start the spool.

I have removed the tab and added holes for the filament start. I also reduced the plastic needed to print by using honeycomb on the flanges. I added a location for a label on the one flange.

Now I rewind directly onto the bobbin without using a separate hub adapter.

It assembles just like the original spool model.
