Elfa Compatible Filament Shelf

Elfa-compatible bracket used to store filament spools (or anything round, really). I use three of these under a 48" wire shelf.

Most people use 8mm rod for these, but I couldn't source the 48" of 8mm rod easily. This version can house 5/16" rod (available at Home Depot in the US) and is a "press fit" It cuts away a bit of the print in the hole, but it's sturdy enough not to need clamps or anything else on the rods.
