LM2596S IDUINO VERSION

By mistake I bought DC-DC converter that doesnt have mounting holes and has diffrent dimensions (21,7mm X 47.3mm), so I came up with new design and made it in few different options. My very bad chinese printer dealt wit a print like boss, so I am sure yours will have no problem to print it as well. Settings i used are still experimental as it is used printer and it has few problems I didnt solve yet.
