I designed this filament shelf to resemble a well-known technical brick but at a much larger scale. Each lift arm can support up to 20 lbs, meaning a pair can easily hold up to 11 rolls of filament. For the axle, you’ll need a ½-inch steel conduit pipe from your local hardware store, cut to the length you need (I cut mine to 32 ¼ inches or just under 82cm). The axle pieces slide onto the conduit to form a giant, axle and snap together without glue. I’ve created two versions of these axle pieces: one at 200mm and another at 100mm. The 100mm version is much easier to print, so I recommend using that one—especially if you’re worried about your bed adhesion.The cleat mount is designed for both strength and a clean appearance, as it hides the mounting screws. To ensure maximum durability, print the cleat mount with 100% infill and at least 3 to 4 wall loops.The width of the shelf is determined by the wall studs, which are typically 16 inches apart. For my setup, I skipped a stud, making the
