Perforated panel - Spool Holder 18mm

Hi ! This is a simple Spool Holder for Perforated panel (originally designed for Ikea Skadis), up to 9 spool at the same time. Requires 18 mm aluminium tubes (wood or PVC can also be used). Hole diameter: 18.2 mm (perfect fit). Need to be printed with PETG at least. Depends on the weight applied on it, a third support should be required to prevent Skadis bending on the middle.
