Modular Desktop Wind Tunnel

A small and simple desktop subsonic wind tunnel that is designed to be printed as modular sections that can be assembled, disassembled, and modified to fit your aerodynamic testing needs or desires.    As designed using all five sections (and a small low cost 6"inch duct fan, arduino uno, 100 g load cell) this wind tunnel accurately measures lift or drag, and can also help visualize air flow with the addition of a low cost “halloween” fogger to simulate smoke.  Ideal for middle school, high school science projects or just for learning/demonstrating simple aerodynamics.
