dektop fan with rechargeable battery

thingiverse

hello, here is one more desktop fan. thanks for the idea and the files (by guppyk). i modified it a bit. i copied the bottom part, moved it and created a space where i put a rechargeable battery and a charging chip. on the right side i added a motor controller to regulate the speed. i replaced the fan wheel. the shape of the new fan blades doesn't push much air to the side, which makes it quieter and more effective.
