3D model description

This thing is part of the rLab unified dust extaction system that connects a PowerKing SBC1 Blasting Cabinet up to the dust extraction. It accepts a rLab unified dust collection fitting version 4 and bolts into the cabinet over the port where the internal filter goes.

It's printed in sections with the base plate clamping onto the cabinet, then 3 of the springs are fitted inside, a spacer to hold them in place, and the hose fitting screwing on top to complete the assembly.

The 3 plastic springs that fit inside the base plate provide a limit on the suction that the system can generate in order to avoid the lid of the cabinet being sucked inwards or the gloves being pulled off their mounts. The tension of the springs can be adjusted from a parameter in in the OpenSCAD file in order to allow stronger or weaker suction.

In order to use this design you'll need to download the files for this thing, the V4_fitting.scad file from the rLab unified dust extract system page, and the threads.scad library file version 2.2 by Dan Kirshner which is available at

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
