All The Air Ducting Parts You Could Ever Need [Hackaday]

View Article on Hackaday

If you have ever planned an air duct or dust extraction system for your shop, you’ll know just how difficult it can be to accommodate all but the simplest of arrangements. Off the shelf systems are intended for use in home heating or other domestic systems, and offer little flexibility of choice. Of course you could 3D print an adapter or two, but [Fabian] has taken it to the next level with a comprehensive library of 3D-printable pipe system adapters and accessories. We’re not sure we’ve seen such a complete collection.

The pipes are mostly at 125 mm diameter, with the full array of elbows and joints, alongside adapters for fans and smaller pipes, and different splitter options. It becomes particularly interesting in the accessories department though, because he’s also made a set of smart addons, packing ESP32s for sensors, and even valves.

It sometimes shocks us to go into hackerspaces and see nothing in the way of extraction around tools that really need it. Airborne smoke and particulates are a proven hazard, and thus we like this project a lot. If you don’t have adequate ventilation or extraction on your bench, consider printing yourself a solution. Take a look at how one hackerspace did it.
