Boot Dryer by Jenz

Boot dryer using a small 4020 centrifugal fan. There's no heating element but the forced airflow will dry at least my sweaty ski boots in an hour or two.
The snouts should be printed with spiral vase and thin wall detection. The top and bottom part can be printed without support material, at least on a Prusa i3 MK3. To fit the fan you'll need to sand down part of the upper mounts on the fan. Use M3 x 35 mm and nuts to bolt the two pieces together. Use two short pieces of filament as hinges for the hooks. For power cord I used an old iPhone charger cord, cut away the lightning adapter and soldered it to the fan. For power supply you can use just about anything that will accept a USB cable. You can either print one and dry one boot at the time but the smart thing is printing and assembling a pair and hook them up in parallell to the USB cable.
