X-Rack for spools

X-Rack is a simple idea of using up unused spare or cheaply available materials to build storage for filament spools. I used uPVC 20mm Conduit that I had lying around and the holes are made for that exactly. The brackets are lightweight but can support good bit of weight. The middle parts are to reduce sagging and are in 3 hole sizes. Bear in mind that some amount of sanding might be still required depending on your filament calibration, materials used, etc. Also you can use any kind of pipe/tube/dowel of 20mm diameter (timber, copper, PVC, steel etc).
