<p>I made the threads with this <a href="https://www.thingiverse.com/thing:193647">http://www.thingiverse.com/thing:193647</a> . I like to keep these hubs on my spools for easy switching of filaments and it fits most of the spools i use including the cardboard ones. For very narrow spools you may need to trim some threads off by slicing a portion off the top of the bolt portion using 3d builder or other software or just by stopping the</p> <p>print. I like the look of the bearings whether needed or not , and I usually buy extras or salvage them from roller blades</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>p802M</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>Doesn't Matter</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>.24</p></div> <p><strong>Infill:</strong></p> <p>I used 15%</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>.printed with .24mm layer height, 15% infill, with or without support .

Snap in 2 608 bearings for a free wheeling spool or don't clear out the inner diameter so there is some resistance.</p> <h3>How I Designed This</h3> <p>I made the threads with this <a href="https://www.thingiverse.com/thing:193647">http://www.thingiverse.com/thing:193647</a> and used sketchup for the rest</p> <p>Many Thanks to Mike_Mattala for NUT JOB | Nut, Bolt, Washer and Threaded Rod Factory</p> </p></p> Category: 3D Printer Accessories
