I started making a Teeny Weeny delta printer after a work trip where I wanted to have a 3D printer available for use. Obviously, this missed the “portable” design requirement by quite a lot, but I'm super pleased with the outcome anyways!
GitHub has a more robust description.
The CPAP effector is currently still being beta tested by me. Updated files will be released when I am satisfied with the end product.
The GitHub description has credit to models used in the build or that I modified.
The author marked this model as their own original creation.
