Tornado Vortex Tube (Customizable)

prusaprinters

<p>This is a very simple tube to create a water tornado. There are no threads so you'll need to use hot glue or epoxy to connect the bottles together. Here are two options: print big enough to glue the caps into the connector or glue the bottles directly to the connector.</p><p>Experiment with different sized nozzle diameters, small diameters are more difficult to get the vortex but take longer to drain.</p><p>Strongly recommend using the Customizer in OpenSCAD, the stl is for a random Chinese water bottle and not the same dimensions as a standard soda bottle.</p><p>&nbsp;</p><figure class="media"><oembed url="https://youtu.be/VxJbpAx9xjI"></oembed></figure><p>&nbsp;</p><h3>Print Settings</h3><p><strong>Printer:</strong></p><p>Raise3D E2</p><p><strong>Rafts:&nbsp;</strong></p><p>No</p><p><strong>Supports:</strong></p><p>No</p><p><strong>Resolution:&nbsp;</strong></p><p>0.2</p><p><strong>Infill:</strong></p><p>30%</p><p><strong>Filament:</strong></p><p>eSun PLA+</p><p><br>&nbsp;</p><p><strong>Notes:</strong></p><p>If you have problems with water leaking out use enough shells to make sure it's water proof (3 or 4).</p><p>Also a great suggestion from <a href="https://www.prusaprinters.org/social/134169-dejf">dejf</a>: Waterproof is easily achieved by hot air melting the surface of print - it requires a good source with temp setting and a bit of experience to see the point of no return to original shape in advance. Also wider perimeters help, because they have lower chance of holes between layers - just try something like 0.55 instead of .45</p><p>Category: Engineering</p>
