This video describes the design- and build process of a small cleanroom space for my workshop. In addition to facilitating working more cleanly, it also allows for working with dangerous substances, such as strong fuming acids, and can be used for processing photoresists. It's build from approx. 5m2 of trespa plate material and uses a HEPA filter and a fan to achieve a steady supply of clean air.
