I need someone to file STEP/STP to make a mold for a flower design. The design is simple, and I have exact dimensions for the mold. I prefer to use metal for the mold material. I am willing to pay $10 USD for the project. Ideal skills and experience for the job include expertise in CAD design and experience with metal mold manufacturing.
