I have wanted to try and design and build a PC fan for some time. I wanted it to be mostly if not all 3D printed. However, I never did because that kinda sounded boring, that is until I see the TMD fan created in the early 2000. That fan was different and sparked the idea of trying to create a fully hubless PC Fan.
