STl and cad design for motorized crimper

My project requires design work in both STL and CAD formats for a motorized crimper. I have a rough idea of the size and shape I’m looking for, but I am open to suggestions. I don’t have a specific timeframe for completion, so I am flexible with respect to scheduling. This project requires an experienced designer who is exceptionally skilled in both STL and CAD formats. Please let me know if this is something you can do.
