Sliding E3D V6 Nozzle Case

<p>This is my take on an E3D V6 nozzle case. I took a look at a bunch of other models of nozzle cases on Printables and none of them really fit my bill:</p><ul><li>Tight Fitment</li><li>No support</li><li>Easy to print</li><li>Full coverage on the sides and not too much leakage</li><li>Easy to slide in and out&nbsp;</li><li>Doesn't need to screw in&nbsp;<ul><li>Nozzles should be able to slide in and out without worrying about threads which can be difficult to print</li></ul></li></ul><p>I designed this case with these requirements in mind, starting with dealing with fitment. I found that some of the sliding rails in other models can be fairly difficult to print as they are direct overhangs, despite being small. Instead, I did a 60 degree outwards slope followed by an inverse 60 degree inwards slope to make a very easily printable sliding rail.</p><p>I also combatted the slop in most other “remixed” case models by designing the case to be direct fit with a 0.2mm tolerance between the cover and the main body. This was fairly robust and tight from my testing, so I added a finger slide strip on the bottom of the cover to easily slide out the body with a push.</p><p>Also, was not a fan of the open design so I made the back entirely enclosed.</p><p>&lt;hr&gt;</p><p>This was designed to fit nine (<strong>9</strong>) E3D V6 nozzles with a 5mm nozzle head size (perfect for SliceEngineering Vanadium nozzles, that I use exclusively), but I can easily release additional models with higher headroom. I found these SliceEngineering Vanadium to be <i>just</i> the right size for these, with about a 0.2mm headroom on top.</p><h3><strong>Print Settings from my tests</strong></h3><ul><li>Raise3D E2</li><li><i>Unreleased</i> PLA+ Black [own brand]</li><li>0.6mm nozzle size</li><li>0.66mm extrusion width</li><li>0.25mm layer height</li><li><strong>Special Concerns</strong><ul><li>I recommend dialing in your z-offset for your first layer on the main body very well. Because this is a sliding fit, any <strong>elephant's foot</strong> will cause major fitment problems. Alternatively, turn on elephant's foot compensation to -0.2mm on contours <strong>P</strong></li></ul></li></ul><h3><strong>Print Orientation</strong></h3><ul><li>Print the main body with the rails pointing upwards and the <i>large flat surface touching the build plate. </i>The holes should be open from the top</li><li>Print the cover with the opening towards the sky</li></ul><h3>Specifications</h3><ul><li>Nozzle Support: E3D V6 (M6 threads), 9 total<ul><li>Note: Hole size was enlarged to 6.2mm to account for even shrinking filaments</li></ul></li><li>Headroom (from shoulder to tip): 5mm</li><li>Threading: None</li><li>&nbsp;</li></ul>
