Toroidal Turbine Desktop Fan

So here is that massively over-engineered, easy to build, super quiet little desktop fan you have been waiting for. I am not in drone design, but still wanted to play around with that MIT toroidal propeller design everyone is talking about. So here is my take on the use of toroidal blades (for everyday life - at least once it gets a little warmer outside). The fan can be powered directly from USB or using a separate (preferably 9V) power supply (which is what I ended up doing as it gives you a little more power). All you need is one of these - 3-9V miniature motors (approx. USD 2) and either an old USB cable OR a - 9V power supply (approx. USD 7) or any old power supply (5-9V) you have lying around. Cut off the end and connect to the cables coming from the motor (that's what this little box at the back is there for). FILAMENT - I use my favorite easy to print Carbon Fiber PLA , which gives that beautiful semi-matte finish, but pretty much any filament and color combination should do. PRINTING Printing should be super easy. No supports needed. I use 30% infill and 0.25 mm layers (except for the propeller, which I printed at 0.1 mm to get a smoother surface). ASSEMBLING should be pretty straightforward. Use two M3 (around 6-8mm) screws to attach the foot to the main body. Use a drop of glue to fix the front to the main body and the small cover to the connection box (once power is connected).
