I apologize if this has been asked before. I got into 3d printing a few months ago and have been loving it. While I have only printed online stl files, I have finally found myself in a position where I want something designed. My wife purchased me a charging pad that came with a clip on section for a smart watch. Unfortunately it is designed specifically for am apple watch and I have Samsung. I want to design the same type of clip on but for my watch instead. How exactly would I go about designing and creating this? Any insight on getting started on 3d file creation for practical stuff would be great! Thank you.
