Wall / Cupboard / Desk Infinite Length Simple Spool Rack

thingiverse

Hi all, I'm always running out of space for my filament spools, so I came up with an idea to stash them behind my desk. It's not just limited to that spot; you could also use it in a cupboard or on bookshelves. To create this storage system, you'll need two sets of left and right brackets made from 20mm plastic electrical conduit (available at B&Q or you can opt for metal). You'll also need a center piece to distribute the weight evenly between the brackets. Each bracket requires four screws to secure it in place. The installation process is a breeze, thanks to the square back of each bracket that allows them to butt up against the surface behind. The flimsy-looking strap between the brackets provides just enough support to hold everything in place while you screw them down, so you only need to measure once per side. When setting up your own rack, keep in mind that mine is 600mm long, with a center support piece at 300mm. However, I think spacing them 200mm apart would be better. Make sure you have at least 200mm of clearance from above the top surface to the top right angle corner of the bracket, or your spools might not fit smoothly. I printed mine in PLA, but ABS or PETG would provide longer-term durability. Still, my setup has held up fine so far since I don't have anything beneath it that could cause issues if it fails. Before you start using the rack, test its weight-bearing capacity. The weak point is likely to be the fixings on the middle supports due to the shear force exerted on small screws in thin material (chipboard).
