3D model description

This is the general dust collection system that's been designed for rLab in order to help keep the dust in the workshop under control. It's intended to provide a unified fitting system that allows us to connect any of the vacuum dust extractors to any of the main dust producing tools. It uses a 50mm ID PVC spiral hose that's suitable for use with vacuums of a variety of sizes, we're currently using with Scheppach HA-1000 units. These designs are intended to be an intermediate size suitable for general workshop use on fixed tools. This system is also in the process of being expanded to include mini-sized couplers for use with hand tools.

This thing contains the generic versions of the fittings along with the OpenSCAD files used to create them so that you can customize your own versions, they are not pre-adjusted to fit any specific tool! If you're looking for the connections that are actually in use at rLab then please check out the collection that this thing is part of which includes some other connectors as well as versions of these connectors that are customized for specific tools. Fittings are mechanically compatible with all other fittings of the same major version number, I.E. a V4.0 hose will connect to a V4.4 fitting, or vice-versa, but a V4.x fitting is NOT compatible with any V3.x fitting

In order to use any of these designs you'll need to download the file for the thing you want, the V4_fitting.scad file, and the threads.scad library file version 2.2 by Dan Kirshner which is available at

Updated 18/9/19 - New version of V4_fitting.scad uploaded including the mini fittings
Updated 23/10/19 - 32mm hose coupler file update, add 32mm mini fitting for hose, add regular to mini fitting adapter

Electronics Engineer from Reading with some Mech.Eng. training. Mostly doing 3D printing for work making assorted parts for high-voltage assemblies but also designing and printing random items I find useful. Strong preference for keeping the entire toolpath open-source but will use commercial software where it's really needed.

I also do a lot of 3D design work for rLab, Reading's hackspace to help with maintaining the supporting the equipment and keeping the building clean.

Issue with this design? Report a problem
