This is a nice way to enhance your home heating by increasing the airflow of the radiator.

Available for different radiator sizes (85-90-95mm top depth). For a full radiator coverage and maximum performace you can adapt it to your radiator length as well, just print as many segments as you wish. For the end-closing pieces I provided the step-models so you can adjust to your specific size/length with the offset face feature in Fusion360. All parts print support-free.

The fans will turn on and off automatically, thanks to the small thermostat switch, which you can stick to the radiator body with a magnet.

The fan inserts are a separate part, this way you can rotate them for the optimal hot airflow direction.

What you will need: 

• 12V AC-DC power adapter with DC plug (if you want to decrease the fan speed and make it quieter, you can choose an adapter, where the voltage can be set between 6V, 9V, etc.)

• 2,1x5,5mm DC-plug with cable-ends, female
