prusaprinters

<p><strong>NOTICE: </strong>this is the first iteration of this design. It might work for you, it might not. If it doesn't, any feedback would be appreciate.</p><p>Filament roller/guide for Creality Ender3 family of printers. Designed to work with <strong>DUAL GEARED EXTRUDER</strong>, not the stock one (or metal equivalent).</p><p>I found a similar one in the past for the stock extruder, but I couldn't find one for the dual geared extruder that has the entry point taller on the z-axis.</p><p>It requires a 608 bearing (I used a ZZ, but any other variant should work as well).</p><p>I have printed it in PLA+, but PETG, PLA, ABS or other plastic material should work as well.</p><p>All the STLs should be in the correct printing orientation and a step file is provided for anyone who wants to make changes.</p><p><strong>PRINT INSTRUCTIONS</strong></p><ul><li>PLA+</li><li>0.2mm layers (you can go higher if you'd like to save a bit of time)</li><li>Support might be required for the arc in the base</li><li>Brim might be required for the spine, depending on your bed adhesion</li><li>6 perimeters walls and 15% infill (if you lower the number of perimeters, make sure to increase the infill percentage for rigidity)</li></ul><p><strong>INSTALLATION INSTRUCTIONS</strong></p><p>Insert the 608 bearing in the wheel (it should fit very snuggly and might require a bit of force).</p><p>Drive the spine piece threw the one of the two towers hole, the bearing and the other side tower in this order.</p><p>The wheel should have enough clearence to move along the spine and align with the extruder under tension.</p><p>Partially unscrew the v wheel stack above the X axis motor.</p><p>If the screw is very tight, you can temporarily loosen the eccentric nut on the opposite side (towards the center of the printer) to loosen the whole X joint.</p><p>Slide the base over the metal frame and re-insert the v wheel screw making sure to keep the nut side towards the back of the printer.</p><p>The base has a notch for the nut easily accessible under the base.</p>
