Spool of Thrones Holder

prusaprinters

<p>Many printers are designed for filament spools of one standard size (0.5 - 1 kg). However, one way for schools to save money is to buy spools in large bulk sizes (I love the 2.2 kg economy spools from colorfabb).</p> <p>However, these large bulk spools will not fit in / on the factory spool holders. This spool holder is beefed up to hold the hefty wide spools.</p> <p>You will need a scrap section of 1/2 PVC pipe or dowel. I've used a broken broom handle as well.</p> <p>I designed this to fit the large 2.2 kg (5 lb) spools from colorfabb. This is high enough to give you clearance for any commercially available spools.</p> <p>This is designed to fit in the channels of the extruded aluminum frame of a Lulzbot Taz 5 / Taz 6. It is a great way to use the vertical space above the printer.</p> <p>Your students can use this on their Lulzbot, or as a stand alone external spool holder for school printers.</p> <p>This can be used to explore architecture and geometry. It can also be expanded to hold more spools of filament.</p> <p>UPDATE: THE SPOOL OF THRONES version of this holder can hold 6 of your tools close at hand. I've had a couple spools get tangled, and I could never find my wire cutters when I needed them, so I put some tool slots in spool holder to hold them close by.<br/> Eagleknot assumes no responsibility for any lust for power and the desire to sit on the cold steel of your fellow 3D printers...</p> <h3>Print instructions</h3><p>Unassociated tags: #DesignProject , #EngineeringProject, #MakerEdChallenge</p> <h3>Category: 3D Printer Accessories Print Settings</h3> <p><strong>Printer Brand:</strong> LulzBot</p> <p><strong>Printer:</strong> <a href="http://amzn.to/2nxubRO">TAZ 5</a></p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> Yes</p> <p><strong>Resolution:</strong> .3 - .9</p> <p><strong>Infill:</strong> 10%</p> <p><strong>Notes:</strong></p> <p>This is a large piece, so watch for warping.</p> <p>Break all sharp edges after printing. The pipe should fit snugly inside the holes, so use sandpaper to smooth out the insides and outside of the pipe.</p> <p>If you have a MOARstruder, this would be a good project to test the thicker layer heights.</p> <h3> Post-Printing</h3> <p><strong>Finishing</strong></p> <p>This is a work piece, so I just use a soddering pen to smooth down any sharp edges. Sand the inside hole and pipe so they form a snug, smooth fit.</p> <h3> How I Designed This</h3> <p><strong>Design</strong></p> <p>This was designed in AutoCAD 2014.</p> <p>It was designed to fit in the channels of the extruded aluminum frame of Lulzbots. This is designed so I can use the large spools and still have the vertical clearance I need with my Taz 5. This can work as a stand alone spool holder as well. These give me easy access to the spool compared to having it on the side of the printer.</p> <h3> Custom Section</h3> <p><strong>Objectives</strong></p> <p>Students will provide service to the school.<br/> Students will maintain 3D printing equipment.<br/> Students will explore arches and triangles in architecture.<br/> Students will explore stress, distributed load, tension, and vibration.</p> <p><strong>Audiences</strong></p> <p>High School, Vo Tech, and college level students.</p> <p>The properties for these files can be explored in solidworks or other professional CAD program.</p> <p><strong>Preparation</strong></p> <p>Students should understand basic geometry.<br/> Students should understand force, loading, and dynamic forces.<br/> Students should understand how 3D printing works, and how to troubleshoot common problems.</p> <p><strong>Steps</strong></p> <p>a. Students should review geometric shapes.<br/> b. Students should review dynamic loading and static loading.<br/> c. Students can test loading by standing on these spool holders. They can compare the forces involved to what computer models predicted.<br/> d. Students can use solidworks to predict and measure stress and loading on them.<br/> e. Students can explore redesigning these to be lighter, use composite material, or have other desirable properties for 3D printing.<br/> f. Students can explore ways to commercially produce these holders, or run a printing farm to produce enough for all the schools printers.</p> <p><strong>Results</strong></p> <p>Students should demonstrate knowledge of 3D printing techniques.<br/> Students should produce functioning spool holders for the school.<br/> Students should understand dynamic and static loading.<br/> Students should modify these to meet the engineering needs for their printers.</p>
