Parametric vacuum hose connector with magnetic connectors.

<h3>OpenSCAD project to create vacuum hose connectors.</h3><p>Intended for generating connections that would allow connecting vacuum hoses and tools of different diameters together.</p><p>Parametric settings support a few connections types. The connections types can be used on ether end of the adapter.</p><p>Options:</p><ul><li>Connector: Hose adapter</li><li>Connector: Magnet hose connector</li><li>Connector: DysonV6</li><li>Connector: Flange</li><li>Connector: Nozzle</li><li>Transition: Straight tapered</li><li>Transition: Angled&nbsp;</li></ul><p>&nbsp;</p><p><strong>Hose connection</strong></p><p>Intended for connection to a hose or a tool.</p><p>Main setting:</p><ul><li>Diameter: Internal or external diameter of the intended connector. If your hose has a 50mm internal</li><li>Length: The length of the connection end.</li><li>Taper: the hose connection can be tapered to allow for a tighter fit.</li></ul><p>&nbsp;</p><p><strong>Flat connection</strong></p><p>Intended for connection to a tool. To achieve this the transition section is set to flat, the transition length becomes the thickness. The flat area will be from connector1Diameter to connector2Diameter.</p><ul><li>TransitionStyle: flat</li><li>TransitionLength: Thickness of the flat area.</li></ul><p><strong>Magnetic flange connection</strong></p><p>Intended for creating a quick removable connection. Allowing the hose to be quickly moved form device to device. The magnets should be slightly recessed so that the two faces get a good seal, allow extra depth if you want to avoid supports.<br>8 10mm x 1.5mm magnets seem sufficient to hold a 50mm connector for a shopvac.<br>Regarding magnets you will need opposite polarities for the faces to attract. Suggest that each connector has alternating polarity, half positive half negative, this way all connectors will attract.<br>An alignment ring can be added to help alignment and air leakage. Suggest the flange include a recess for the ring, then if wanted you can print a ring in TPU to assist with air leakage. Does not appear to be required.</p><p>Note, changing any of the settings (diameter, magnet size, alignment ring...) will change the magnet position and flange size. Suggest settings are written down for future connectors.</p><p>Main setting:</p><ul><li>Flange diameter: Internal diameter of the flange connection.</li><li>Flange thickness: The overall thickness of the flange. Magnet thickness plus 4mm seem to work well.</li><li>Connector length: The length of the connector before the tapered section will start.</li><li>Magnet count: Number of magnets to be added to the flange.</li><li>Magnet diameter: Diameter of the magnets (add 0.5 to measurement).</li><li>Magnet border: The amount material around the magnet.</li><li>Magnet thickness: Thickness of the magnets (add 0.5 to measurement, 1.0 to avoid supports).</li><li>lip: If an alignment ring should be supported, can be recessed or protruding, suggest recessed.</li></ul><p>If you cant use OpenScad, and want a specific adapter let me know.</p><p>Project homepage <a href="https://github.com/ostat/vacuum-hose-adapter-openscad">https://github.com/ostat/vacuum-hose-adapter-openscad</a><br><br>2022-09-26&nbsp;</p><p>Updated to support angled transition</p>
