Ender 3 spool holder extension

prusaprinters

<p>A spool holder extension that simply plugs into the original one. I designed this to be able to use some wider spools (like from PM) without risking them falling off.</p> <p>You can use it with or without the nut in the middle, depending on what your spool requires. The extension just clicks in place when inserted all the way through.</p> <p>It is an extension, not a replacement, for a simple reason: better load capability. The original tube is very rigid, but short. Using an extension that runs through it, I use it to support the extended part, dramatically reducing forces that could cause layer separation on the printed piece if it had a similar overall length. Therefore it should hold multi-kg spools easily.</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</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>10% Cubic</p></div> <p><strong>Filament:</strong> Filament PM (Plasty Mladeč) PETG Transparent Blue</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Unless your bed adhesion is horrible, no raft or brim is needed. PETG is preferred, but PLA should work too. Simply print in the supplied orientation.<br/> Use at least 1.2mm walls and 1mm top/bottom thickness for rigidity. <h3>Post-Printing</h3> <p>No postprocessing needed. Simply slide it into the original spool holder tube from the back until it clicks in place. Remove the original nut first if necessary for your spools.</p> <h3>How I Designed This</h3> <p>Designed in FreeCAD, the file is included for potential remixing ;)</p> </p></div></p></p></p> Category: 3D Printer Parts
