3D Cad/Cam design for consumer product

“Zvonko is very responsive and if you give him a design, he will quickly create a CAD file for it in multiple formats. He's very quick and easy to communicate with. I needed more help with tweaking my design to make it more easily manufactured, however, as I didn't know much of the basics in injection molding. Zvonko won't give much feedback on how to make the design more manufacturable, but he will take your design as is and translate it really well into CAD.”
