I'm new to the Shapeways customs and haven't ordered anything yet. However I am looking into a few things but want some experienced opinions. Looking to get the Prime wheeljack blasters, but I am wondering which material to order for the best look, and really what difference there is to them. Also what are a couple other things from there t&t have been great? I appreciate the feedback and apologize if this shouldn't be here as its essentially custom items.
