This fan design was quite popular with my youtube audience and it's a perfect starting point to learn to integrate electronics and 3D printing together for functional open source design assemblies!

This is an exemplary model for open source design, with fully open native CAD files, full documentation of the feature tree with named features, and photographs that demonstrate the trial/verification of the parts. Unlike most, my CAD models are designed for customizing freely, with mostly parametric sketches to simplify modification with a few global variables. Essentially, these models are engineered for adaptation.

This is my first model as I test out makerworld. All my designs are functional, tested, designed for manufacturing, and most of them are parametric for easy adjustment. Cheers from David!
