If you are tired of wet boots you can actually make a boot dryer yourself.
You probably know that leather shoes and boots should not dry at the heating devices. They should dry at room temperature. So we are not going to heat, we are going to ventilate.
What can be boots ventilated by from inside? With low-power fans. CPU cooler ones are perfect for that! If you don't have any, they are quite cheap. By the way, some are even illuminated.
Those we are going to use have power of 12 volts.
They are a bit different, but it doesn't matter.
Now we need a suitable power supply unit. Then we connect all the stuff anf check if it works in the way we need.
Now we are making the very construction of the dryer. It should consist of canals supplying air flow from the fans to the inside of the boots. The water plastic pipes with rubber seals are a perfect choice. They are available in different sizes and cheap.
