The 3D Printed Loop De Loop•••This is something I’ve spent a surprising amount of time trying to figure out- how to 3D print a smooth loop where the layer lines travel along the profile of the loop. If I were trying to print this on it’s own, the loop would either need to be printed vertically which would require supports. The tracks would also be stepped resulting in a not-very-smooth solution. Alternatively, if printed on its side, you would again need support material, or you would need to ex
