Hanging filament roller

prusaprinters

<p>This is a simple hanging filament spool roller with two versions of the support frame. One version (hanging_filament_roller1.stl) hangs on a vertically mounted bracket (like the one provided with some Creality printers). The other version (hanging_filament_roller4.stl) uses a 4 or 5mm T nut to attach to a 20x20 frame.</p><p>The roller that fits in the frames is formed from two copies of the part “hanging_filament_roller2” joined by the part “hanging_filament_roller3”, a short rectangular bar in a press fit.   A 608 style bearing fits on the nubs on either end of the roller.</p><p><strong>9/5/2021 update</strong></p><p>I also have included an offset, 20X20 mounted, reverse bowden mount (ext rev bowden mount.stl) I use with the hanging roller used on my Creativity ELF. It uses two PC4-M6 pneumatic fittings. You probably want to drill/ream the 2mm bore to ensure easy filament movement. It is offset to avoid filament rubbing on the spool edge. </p><p>I later replaced it with a version that has the bowden passthrough at a 22.5 degree angle for better function (rev bowden mount-22-5).</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Creality</p><p> </p><p><strong>Printer: </strong></p><p>Ender 3</p><p><strong>Rafts:</strong></p><p> </p><p>No</p><p> </p><p><strong>Supports: </strong></p><p>No</p><p><strong>Resolution:</strong></p><p> </p><p>200</p><p> </p><p><strong>Infill: </strong></p><p>20</p><p><br/><strong>Filament:</strong><br/>PolyMaker PETG <br/> </p><p><strong>Notes: </strong></p><p>No supports are needed.
