A fun loving project esp. for beginners includes scratch which is readily available and cheap. But it doesn’t end the possibilities of learning as such projects includes soldering, which must be performed in a well-ventilated Environment or possibly under guidance. It allows you to learn as well as experiment at the cheapest cost available.

Soldering can be serious health hazard as the flux generates the visible fumes. Hence, it is recommended to use a fume extractor during soldering but they are really expensive. In this tutorial of Instructables, you will learn to make a fume extractor that cost around 5$ but works like a charm. Further, it can also be used for 3D Printing ABS, as it fumes and also toxic in nature.

This Fume Extractor is not only cheap and portable but it purifies air completely and comes with adjustable Legs. The equipment used here are salvaged, which includes activated carbon Filter, DC fan, M4 Nuts and Bolts, Switch and DC jack. The tools used are Glue gun, Soldering Iron and 3D Printer Link.

The filter is prepared by cutting the activated sponge into the required part. Then, start by tracing the outline of the fan and repeat this until it cut the sponge completely. Now, with the Grill, Glue the Dc Jack and the Switch on it. The cabinet is cut down with a Dremel and then painted with spray.

As shown in the diagram, the red wire is soldered to the +V and Black to the Ground .The Red wire is then soldered on the switch and from the switch, another wire is connected to the other terminal of the switch and the positive terminal of the fan. Then, the black wire from the jack is connected to the negative terminal of the fan.

The leg was designed in a manner that could be easy to use and also the height could be easily changed. The final design is shown above in the picture and the whole model was designed in Autodesk fusion 360.
