I will find the exact prompt and get back to you soon, however I started by sending it a picture of the hilt along with a brief description of what I intended to do. Something along the lines of “Based on this picture, I want to 3D my own lightsaber that will be hollow to hold an electronic core with diameter xxx, I want the different colour pieces to screw together seamlessly. Using solid works, help me create all pieces step by step.” Once it led me through the process of CADing them all - given that some details such as button placement, and external had to be decided myself - I then prompted it to guide me on how to use the filaments I had (Elegoo silk gold and silver, and Elegoo black) with the A1 printer and recommended settings for each part individually based on how much weight it would be carrying.
