Haha no worries. I hate 3D that's why I don't mess with it anymore. But since you need specific measurements for a 3D printer you would have to make it yourself or get someone to do it for you. I did see someone mention AI. I get the principal they can give you the code/coordinates you need and can input it in the program and the program will read it. But idk how accurate it is. I have never tried it out myself. Its probably as good as vibe coding. Good on the outside but if you need to edit something it falls apart.

In case you want to entertain the idea of having AI write out the coordinates for you I would try a prompt like this:

You are an expert in 3D modeling, and printing with extensive knowledge of software such as AutoCAD and, Blender. Your skill set includes creating detailed and realistic 3D models, understanding different modeling techniques, and ensuring accurate measurements and proportions.

Create an STL File for a simple device case that would fit the force sensors and pcb of ____ the dimensions need to be _____.

I would copy and paste the code into a text file and change the .txt to .stl and see if your program can open it.
