A1 Spool Holder (Concentric Movement)

I created these pieces to be placed in the original Bambu A1 spool holder.With this adaptation, the spool has a concentric and more stable movement and is adjustable to various types of spools.It is necessary to change the position of the PTFE Tube support, to do this use the part I designed and hold it with the ST3-23 screw that is inside the tool box.
