OpenSCAD project to create vacuum hose connectors.Intended for generating connections that would allow connecting vacuum hoses and tools of different diameters together.Parametric settings support a few connections types. The connections types can be used on ether end of the adapter.Options:Connector: Hose adapterConnector: Magnet hose connectorConnector: DysonV6Connector: FlangeConnector: NozzleTransition: Straight taperedTransition: AngledTransition: 1 to many Hose connectionIntended for connection to a hose or a tool.Main setting:Diameter: Internal or external diameter of the intended connector. If your hose has a 50mm internalLength: The length of the connection end.Taper: the hose connection can be tapered to allow for a tighter fit. Flat connectionIntended 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.TransitionStyle: flatTransitionLength: Thickness of the flat area.Magnetic flange connectionIntended 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.8 10mm x 1.5mm magnets seem sufficient to hold a 50mm connector for a shopvac.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.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.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.Main setting:Flange diameter: Internal diameter of the flange connection.Flange thickness: The overall thickness of the flange. Magnet thickness plus 4mm seem to work well.Connector length: The length of the connector before the tapered section will start.Magnet count: Number of magnets to be added to the flange.Magnet diameter: Diameter of the magnets (add 0.5 to measurement).Magnet border: The amount material around the magnet.Magnet thickness: Thickness of the magnets (add 0.5 to measurement, 1.0 to avoid supports).lip: If an alignment ring should be supported, can be recessed or protruding, suggest recessed.If you cant use OpenScad, and want a specific adapter let me know.Project homepage https://github.com/ostat/vacuum-hose-adapter-openscad Related modelsHose Fittings collectionParametric model (used to generate all the below models)Vacuum nozzles for all common hose sizesVacuum hose flanges to connect to flat surfacesDyson V6 hose attachments Vacuum hose adaptersStraight hose adaptersY connector / splitter for all common sizes 30° elbow hose adapters30° tapered elbow hose adapters 45° elbow hose adapters45° tapered elbow hose adapters90° elbow hose adapters90° tapered elbow hose adaptersMagnetic Hose connectors50mm magnetic hose connectors100mm magnetic hose connectorsBarbed tube connectorsTube Fittings 4mm-24mmVacuum hose to tubing adapters for all common sizesTube Y connector / splitter fittings 4mm-24mm2022-09-26 Updated to support angled transition2022-12-06Added support splitter transition (one hose to multiple hoses).Added transition base, to make printing 90deg bends easier.Added hose barbs, for assisting with gripping.
