Minimalist 3D Printed Fume Extractor

cults3d

Breathing solder fumes can cause serious health problems, making it essential to minimize their inhalation with a reliable solution. A solder fume extractor is an affordable and straightforward way to achieve this goal, aligning perfectly with my requirements, which is why I designed and built this minimalist, mostly 3D printed fume extractor. My primary objective was to create something both functional and aesthetically pleasing, yet inexpensive, compact, and simple. This project's key feature is the removable filter cartridge, allowing for effortless changes of the activated carbon filter and compatibility with filters from popular Hakko extractors, such as the 491, 493, and FA-400 models. To minimize post-processing, I designed a two-part system for the enclosure and cartridge, eliminating the need for supports during printing and minimizing the time required for post-processing.
