One of the products I make is the TD-IO. It has for a while needed a protective shell both for in cab uss as well as transport and storage. A relatively nice 3d printed one was floating around but the files were never made available and it was only being sold. To renedy this i designed up a case that can be 3d printed for it and am posting it a few places fkr anyone who would like to print one. There is a light pipe that is also 3d printable and it works pretty well if printed in a clear filiment.
