Spool-Upcycling for MasterSpool Refills

prusaprinters

<p>Remixed <a href="https://www.thingiverse.com/thing:2782912">techam's upcycling nut &amp; bolt-system</a> to work with some additional spools. I included the original and unmodified bolt for simplicity.</p> <p>The follwing spools are available for MasterSpool upcycling and<strong>are tested to work</strong> with MasterSpool-refills from DAS Filament:</p> <ul> <li>Tiertime/Cetus/UP Fila 700g Spools</li> <li>Verbatim 1kg Spools How-tos for each individual spool type can be found below.</li> </ul> <p><strong>Don't forget to:</strong></p> <ul> <li>clean your spools after all the work to avoid dust getting into your nozzle</li> <li>anchor the inner end of the filament refill while assembling the spool</li> <li><p>cut the cable ties before printing I really can recommend the Verbatim spools as source for MasterSpools. Easy to work with, already has some slots to prevent the two halves from spinning against each other, the hub can be unmounted completely so even a custom hub would be possible for larger refills like &gt; 1kg (1 kg would probable fit without modifications, for the smaller 850 g refills one side has to be trimmed down a bit).</p> <p>Untouched files from the original are prefixed with original_ and the OpenSCAD-Scripts are included for own experiments.</p> <h3>Print Settings</h3> </li> </ul> <p><strong>Printer:</strong></p> <p>Cetus 3D MkII</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>Doesn't Matter</p></div><strong>Supports:</strong></p> <p>No</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>Layer 0.2 mm, Nozzle 0.4 mm</p></div><strong>Infill:</strong></p> <p>13 %</p> <h3> <strong>Filament:</strong> Verbatim PLA <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>Print the parts upright with the flange on the printbed (requires manual rotation).</p></div> Tiertime/Cetus/UP Fila 700g Spools</h3> <h3> <p class="detail-caption"><strong>Tiertime/UP/Cetus 700g spool original</strong></p> <div><ol><li>Saw the spool apart diagonally as shown in techam's <a href="/thing:2782912" rel="nofollow">original version</a></li> Print the bolt and the nut which indicates this spool <p class="detail-caption"><strong>Not the nicest cut but it works flawlessly.</strong></p> <p class="detail-image"><img src="https://cdn.thingiverse.com/assets/37/ff/3f/fa/37/DSC00425.JPG"/></p> <p class="detail-caption"><strong>Mount the nut, place the filament while fiddling the inner end of the filament into one of the holes, then put the top and bolt on.

You can do this by hand and metal saw or use a table saw if available Shorten the hub-mount on one of the spool sides by about 7 mm, see picture below Mount one side back onto the hub, make sure the fingers lock nicely Print the bolt and the nut which indicates this type of spool The friction fit of the spool itself is pretty good and could be used as such. The nut and bolt provide some security though.</ol></div></p> <h3> <p class="detail-caption"><strong>One side is unmodified, the hub has been trimmed down to 46 and has been mounted back onto the unmodified side.</strong></p> <p class="detail-image"><img src="https://cdn.thingiverse.com/assets/3a/bc/2d/0d/d4/DSC00414.JPG"/></p> <p class="detail-caption"><strong>One side has to be cut down by some mm. I trimmed just short of the locks which is about 7 mm or so. I left the locks which provide a good friction fit.</strong></p> Change Log</h3> <h3>2019-04-27</h3> <p>Initial release.</p> <h3>2019-04-28 16:52</h3> <p>Fixed bug with Verbatim nut - play wasn't correct (could be fixed though by just cutting some protruding plastic from the axle hole of the spool).</p> </p></p> Category: 3D Printer Accessories
