Great means for having custom 3D printed items made. Very cost effective for low volume runs. Plenty of vendor choices provided. Ordering process was a bit cumbersome. I couldn't determine if there was a means of adding additional items to the same order for multiple colors. Doing so seemed to simply increase the quantity of the same color. I ended up placing 6 separate orders (one for each color), but the added shipping costs were credited without requesting it, so it's all good. There may be a means to do so, but if so, it wasn't very intuitive. Other than that, a very good service.
