Metal Shelf Ender 3 Spool Bracket

This is a bracket I designed to fit ULINE metal shelf. I will adapt the ender 3/5 spool holder to hang from the metal shelfs. This allows the repositioning of the spool holder on ender printers. The hardware that is needed is just some 4/5mm bolts and washers. The hardware I used was purchased from Harbour Freight but would be easy to find at any hardware store. “Note” that I do not know if this will work with cheaper brand shelf on amazon.
