Dryer

The dryer can be adapted to P's dryer box or purchased independently as a rice bin. It is compatible with a 24V PTC heater, a 60 fan, and a W3230 temperature controller. It needs 6 M3 screws. Tested by myself and no problem. A1 mini can print it. (Note: when purchasing a power adapter, you need to tell the customer service that it is with a PTC heater. Some surveillance power adapters cannot support it, I have already stepped on this pit.)

The following are the PTC and power supply I use. As long as you use a 60 fan, you can buy it separately. (Link for the lazy)
