It actually creates quite a breeze and will rewind the string from inertia so you can keep going indefinetely!
Obviously every second pull will blow backwards on your hand but it's still pretty fun and effective. It could possibly be improved with a variable pitch fan in the future.
Requires
- ~40cm of thin string (strong sewing thread recommended)
- a small piece of filament.
Assembly:
- fit fan blades and shaft together
- insert into grip
- insert a piece of filament or a toothpick into the lower hole on the shaft
- attach string to upper hole in the shaft and thread it through the hole in the grip
- (optional) attach free end of the string to the pull handle
I printed with PLA and a 0.6mm nozzle, should print well with most any filament and settings.
