5m flashforge spool holder.  I remixed a wall mount spool roller mounts to 2 unused threaded holes on right side.  I am using this with the slim shaddy  Enclosure.  It will also be good upgrade to stock 5m.  Uses 608 bearings.  mounting holes will need to be opened up to 4mm.  I just drilled out after printing.

UPDATE second spool holder now available that prints in one piece no bearings needed.
