Modular Radiator Heat Redirector

This is my first go at designing something from scratch.

The purpose of the device is to sit on top of a standard 2 bar UK radiator to re-direct the heat forward into the room rather than it just going straight up.

I've tried to make it modular so that you can plug as many together as you want depending on the size of your radiator.

I've not printed mine yet, but I'm recommending ABS as PLA may start to warp once the radiator gets up to temperature.

I'd be interested to see peoples prints.
