What are you using to make these? And is the software free?
I'm using SolidWorks (which is used for mechanical drafting or machine design). It's not the best for games, it can be a pain to export it to the appropriate file. Plus, it's $100+ for the student software and $5,000-$20,000 for the full business license

Though If you're rapid prototyping I would charge at least $200/hr
