Elfa Compatible Filament Shelf

thingiverse

I use ElfA-compatible brackets to store filament spools under a 48-inch wire shelf. I prefer these over other options because they can hold five-sixteenths inch rod. Most people use eight-millimeter rod for this purpose, but it was hard to find that length of eight-millimeter rod in my area. This design works well with the available five-sixteenths inch rod from Home Depot and is a press fit. The cutout around each hole leaves a small amount of extra space, making the bracket sturdy enough without needing clamps or other supports on the rods.
