Ender 3 Spool Holder Mod

prusaprinters

<p>I recently purchased an Ender 3 Pro on auction. Some of the filament spools I had, had a smaller hole so the standard Ender 3 Spool holder would not fit at all. (See the fiirst 2 pics. )</p> <p>So I designed this new rod that is thinner but uses the fixing nut of the original Ender 3 spool holder as well as a nut to keep the spool in place. (See pic 3)</p> <p>The rod screws down exactly like the original one except I can now load my spools with the smaller central hole.</p> <p>The rod should be printed with &gt; 50% infill to make it strong and printed vertically.</p> <p>Supports are needed only on the bottom most part where the original Ender nut is screwed on.</p> <p>Important: Do not use a RAFT ever. But use a BRIM of 4 mm touching the model for stability.</p> <p>The nut can be printed with 20% infill and no supports.</p> <p>I have included my Sketchup files for anyone who needs to mod this.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3 Pro</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>200</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20</p></div> <p><strong>Filament:</strong> Generic PLA Orange Post-Printing =============</p> <p>Some cleanup will be required as the bottom part uses supports. Also a little sanding for the bottom part is needed as the tolerance is very fine for the Ender fitting.</p> <p>Once printed and the Ender 3 nut fits properly, it can replace the original rod for the Spool holder.</p> <h3>How I Designed This</h3> <p>Used Sketchup.</p> </p></p></p> Category: 3D Printer Accessories
