Parametric vacuum hose connector

Updated 2025-03-01 - General improvements, added threads (beta).

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.

The project is actively maintained by myself. Please submit bugs and suggestions at the GitHub repo. ostat/vacuum-hose-adapter-openscad .

Connector types

Hose connector The hose connector is the most generic connector. Its intended to be pushed inside a hose or over an existing connector. We can enable a stop to prevent the adapter being pulled in to the hose, and barbs for soft style pipe.

Options

- Length - The length of the connection end - Diameter - Internal or external diameter of the intended connector. - Taper -  Tapered to allow for a tight push fit - Barbs - Stop Official Documentation

Nozzle

A configurable nozzle

Options

- Nozzle Shape - square: a square tip, where you can control the width and depth of the tip, and the corner radius - circle: A round tip, where you can control the radius. - Nozzle_Size - Size of the nozzle tip, in the format of [width, depth, length] - Wall Thickness - Nozzle_Radius - Nozzle_Offset - Nozzle_Chamfer_Percentage - Nozzle_Chamfer_Angle Official Documentation

Flange

Customisable flange for attaching to boxes or wall.

Options

- Flange_Width - Width of Flange added to the connector diameter - Flange_Thickness - Thickness of the flange - Flange_Screw_Position - Position of the screws added to the connector diameter - Flange_Screw_Border - Minimum amount of the material around the screws - Flange_Screw_Count - Number of Screw holes flange - Flange_Screw_Diameter Official Documentation

Magnetic flange connection

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.

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.

Fixed connectors

Connectors that are not configurable as they are designed to be compatible with an existing connector type.

Options

- Dyson V6 connector - Compatible with Dyson V6 vacuums. - Doco - CAMLOCK connector - Compatible with PeterH's - camlock connectors Doco - Dewalt DW735x - Dewalt DW735 Planer - Doco - Cen-Tec quick connect - Cen-Tec Female - Cen-Tec Male - Doco - Makita quick connect - Makita quick connect compatible (not tested) - osVAC - osVAC M32 - Male connector compatible with Original osVAC - osVAC Male - Male connector compatible with Original osVACneo, support variable diameter - osVAC F32 - Female connector compatible with Original osVAC - osVAC Female - Female connector compatible with Original osVACneo, support variable diameter - Doco

Transitions

Using the above listed connectors we have a few options of how to transition between the end1 and end2.

Options

- Transition_Style -  taper+bend: Taper then bend - bend+taper: Bend then taper - organicbend: fully tapered bend - hull: Hull for multiple end count - flat: basic flat transition. - Transition_End2_Count - one to many adapter

There are many other options available,

Support for three unique connectors

Updated 2024 to add support for an adapter with three different connectors.

When using the Hull transition. You have the option to add a center adapter. This third adapter can be, end1, end2 or end3. (previously it could only be end2)

- pink, end1 - blue, end2, you can adjust the angle and count. - purple, can be end1, end2 or end3
