Filament Lock

<p><em>Note: I've used this Filament Lock and my <a href="https://www.thingiverse.com/thing:3627765">Filament Retainer</a> for more than a year. I have found the Filament Retainer design to be better suited to my requirements. I have recently updated the <a href="https://www.thingiverse.com/thing:3627765">Filament Retainer</a> by adding a nose to prevent catching on spoked filament spools.</em></p> <p>1.75 mm Filament Lock</p> <p>This is an improved filament lock to prevent unspooling and tangles.</p> <p>This better meets my original requirements over my <a href="https://www.thingiverse.com/thing:3627765">first design</a>.</p> <h3>What I need in a filament clip:</h3> <ul> <li>No clipping to the spool rim ✔</li> <li>A flag that identifies the loose filament end ✔</li> <li>Prevention of loose filament tucking under another filament loop ✔</li> <li>No need to remove the clip when using the spool ✔</li> <li>Work with any spool ✔</li> <li>Easy to print, no assembly ✔</li> <li>Easy to use ✔</li> </ul> <p>The first design works but I found that on some spools the retainer could slide and allow the filament to loosen on the spool. I encourage you to try this one.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>HyperCube Evolution</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>.2</p></div> <p><strong>Infill:</strong></p> <p>40%</p> <p><strong>Filament:</strong></p> 3D Solutech PLA <p>Whatever color you like.</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>The 40% fill is to give the small area protrusions some additional strength.</p></div> How to use ========== <h3>To store filament</h3> <ol> <li>Insert the filament through the guide</li> <li>Wrap loose end of filament around the spool once or twice</li> <li>Insert end of filament into the "S" lock</li> <li>Slide the filament lock to tighten the filament onto the spool</li> </ol> <h3>To print with filament</h3> <ol> <li>Pull filament out of the "S" lock</li> <li>Lock can be left on the spool with filament threaded through the guide</li> </ol> <h4>The guide inside diameter is large enough to allow filament to pull easily through the lock.
