SKADIS Spool Holder

I made a slim filament roll holder for the IKEA Skadis system.The holder can be attached from the highest hole on the skadis. Then for the next row use the holder without a screw cutout.I use it on a 560mm wide skadis.You also need a 20mm diameter wooden rod. It can be secured from the side with a wood screw.Edit:Add: Center support holder for long versionCenter holder for merge 2 skadis plate
