Door Spool Rack

prusaprinters

<p>Been repurposing my empty filament spools for yarn and needed somewhere to store them, and make it easier to transfer onto smaller bobbins. All the other “door hooks” I could find sit flush against the door, and wouldn't work with spools, so I designed this.</p><p>It holds spools a distance from the door so they can spin freely, despite being designed to hold the weight of yarn, it should be stout enough for a rack of filament depending on what you use for the bar.</p><p>Fits a standard indoor hollow core door, about 34mm is what I measured mine at. Holds a bar up to 40mm. I actually printed 4 pipe extensions and an end from Adafruit's “Yet another keyblade” found here: <a href="https://www.thingiverse.com/thing:3582947">https://www.thingiverse.com/thing:3582947</a> and it holds up well, but I would definitely choose an old broom handle, dowel, or something else if you plan to store heavier things like filament.&nbsp;</p><p>Also, it prints at 15mm, use the scale function in the slicer on Z to scale up to 20mm or more for added strength. I suggest 4 perimeters and 100% infill to reduce flex at the top hook. I've added the gcode to print on an MK3S/+ sliced with my recommended settings, and is what I used for mine.&nbsp;</p>
