Modeler → It is formed from "model" (from Latin *modulus*, meaning a small measure or standard) and "-er" (meaning a person who). A modeler is a person who creates or works with models, often in design or representation.
Think of a 'model' as a small representation or standard, and the '-er' indicates a person. So, a modeler is someone who creates or works with these representations.
