This is a boot dryer made to fit with a Sony SFF22C blower fan.
The air duct is designed to be press fitted again the fan air output.
A 9-11vdc 1.5+ amp wall adapter can be used to power both fan or a 12v battery*.
*The fan will run a 12vdc but for long term use I recommend lower voltage
I printed this thing standing up which requires more support but a greater overall finish.
The raft is to help it stick to the build plate because this thing is about 7'' high or 17.78cm
