3D Printable Plastic Heatchanger Basic Cross Layout 3D print model

A simple heatchanger that can be 3d printed because of it's ability to create fine and complex structures with large surface areas 3d printing seems somewhat interesting for thermal/cooling technology on the other hand most 3d printed materials have a rather low thermal conductivity - there are aluminum printers but the usual plastics have a rather low thermal conductivity however heatchangers which transfer heat from one liquid to another without mixing them are slightly but not quite as dependent on material conductivity as other parts so I designed a little printable heatchanger it's central cube is about 60mm and depending on printing material can reach over 30W/k of heat transfer
