Radiator fan case 3D print model

This is a way of making Radiator heat more efficiant. sitting on top it sucks up the heat pushes through out the room, using old PC Fans and a old power supply. I have had this in my room now for last 6 months, although it does not increase room temperature it enables quicker warming of room and more equal distribution of heat feeling warmer.This can also be adapted for summer sat over ice
