Ender 3 v2 / Pro Filament Guide Remix

prusaprinters

<p>This is in essence still the great design idea for a filament guide by CHE3SE (<a href="https://www.thingiverse.com/thing:5193117">https://www.thingiverse.com/thing:5193117</a>).</p><p>The only part I redesigned is the base. It is fully compatible with the barrel, pin and pin holder designs from CHE3SE. You can either print the complete set or only the modified base.</p><p>The modifications of the base include:</p><ul><li>Increased diameter of the screw holes, so no need for tapping through them or enlarging them after the print.</li><li>Redesigned the two screw holes as slots for easier installation/dismounting of the filament guide. It's still a bit finicky because of the washers, but nonetheless a slight improvement over needing to fully unscrew the existing connection with the associated risk of the brass bearing for the Z-axis falling down/apart. The friction provided by the tightened screw connections is enough to keep the filament guide in place, because the acting force of the filament on the barrel is not pulling the guide in the opposite direction of the slots.</li><li>Increased the clearance between the base and the extrusion spring handle. I found the original design to be a bit tight in that area for my Ender 3 v2 model, leading to unwanted strain in the base.</li><li>Redesigned the primary load path within the base and tried to get rid of as much excess material as possible, resulting in a more aggressive looking part. For the same print parameters (50% infill) I get more than 25% weight reduction compared to the original design.</li></ul><p>Again, all thanks go out to CHE3SE for inspiring my first remix in the 3Dprinting community.</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Creality</p><p><strong>Printer:&nbsp;</strong></p><p>Ender 3</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>No</p><p><strong>Resolution:</strong></p><p>0.12mm</p><p><strong>Infill:&nbsp;</strong></p><p>50%</p><p><strong>Filament:</strong> Ender 3 v2 included filament PLA white</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: 3D Printer Accessories</p>
