Build duct fan

Hi. I live in a country where I do not have access to many facilities and cannot afford to shop online. I am planning to build a 70mm EDF without using a 3D printer. Are there any guides?

I would look at prop in slot jets first, many of the FT designs are done that way, it’s much easier than trying to make your own EDF and can give you a jet flying feel with smaller, easier to get electric motors and props. Even those cheap 2212 motor and prop combos work in slot type set ups.
Big EDF’s like that also need large 6s batteries which will be hard to get.
