Human Powered Hand Cranked Mini Blower

Note that this model is printed 50% smaller than its original size. The idea was to create a compact version, which also reduces print time significantly. It's functional and fun, but not very practical for everyday use. If you decide to print one for yourself, be aware that the fan requires support during printing, while the rest of the parts don't need any special considerations. Printing at full size will require 3/16in rod for axles or an equivalent-sized bolt, as well as some glue to hold the fan cover in place. However, I printed it at 50% smaller and couldn't find suitable bolts at my local hardware store that were both small and long enough for the job. In this case, I used brass nails that I had on hand, held together with glue, which worked surprisingly well.
