Spoolholder 10mm Axle 2020

prusaprinters

<p>After getting a Tronxy X5 I needed to extend my spool holder mechanism to 2020 extrusion based systems, but I could not find a simple solution which fit into my ecosystem.</p> <p>For my other printers I use a 10mm axle and simple axle mounts to store and hold the filament spools.</p> <p>Just use two 4 or 5 mm t-nuts and two matching 10mm screws to mount the holder onto the printers frame.</p> <p>Here my other files to be used with this kind of mechanism:</p> <p><a href="https://www.thingiverse.com/thing:2504710">https://www.thingiverse.com/thing:2504710</a><br/> <a href="https://www.thingiverse.com/thing:2503185">https://www.thingiverse.com/thing:2503185</a><br/> <a href="https://www.thingiverse.com/thing:3363543">https://www.thingiverse.com/thing:3363543</a></p> <p>And a matching filament guide and backlash prevention system as seen on the images above. No need for any bearings or other complex mechanisms. The PTFE tubing keeps the filament aligned, straight and prevents backlash on retract or when fast movements towards the spool take place.</p> <p><a href="https://www.thingiverse.com/thing:3930857">https://www.thingiverse.com/thing:3930857</a></p> <p>All I needed was a simple mount for dropping the spool onto. I am not a big fan of using spool holders with bearings. In the end you need filament guides and other stuff to avoid the rolls from unwinding them self due the no friction policy.</p> <p>This works fine. I made the mount without side walls, so the axle can be mounted from both sides and there is no left or right. It is even possible to cascade them by using three mounts to create two or more spool holders.</p> <p>As always: FreeCAD source file included.</p> <p>Update: I replaced the initial design by a more rigid and better designed one. This one is far more stable at the base. I also added a 0.5mm to the axle radius. This should avoid that the axle is rubbing on the holder causing it to drift sideways.</p> <h3> Print Settings</h3> <p><strong>Printer:</strong></p> <p>Tronxy X5</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div><strong>Supports:</strong></p> <p>No</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2</p></div><strong>Infill:</strong></p> <p>15%</p> <p><strong>Filament:</strong> Janbex PLA Black <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>This is intended to be printed standing on the print bed.</p> If you have a CoreXY or a printer like the Tronxy X5 where the bed is not moving sideways, you are good without a brim.</div></p> <p>For all other printers I suggest using at least a 16mm brim or print it flat on the bed. Then, of course, you need supports.</p> </p></p> Category: 3D Printer Parts
