This is my attempt to fix groggy mornings by lowering my bedroom CO2 from 1700 ppm to ~900 ppm.
I designed a simple, 3D-printed fan duct that directs air under the door to improve air circulation.
A note on the design process: I used CadQuery, a Python library for creating parametric 3D models. I didn't know tools like this existed and highly recommend it if you can program; it turned out to be more convenient than manually iterating on prototypes in a GUI.
The project is open source and the post explains the full build. Happy to answer any questions.
Just kidding. But would you mind sharing what you find so compelling about CadQuery?
As a mechanical person, these code to CAD tools make as much sense to me as suggesting you should write programs with a compass and straight edge.
