I had just bought an rc crawler, and needed some bumpers custom made, because no others would fit my body. I cad designed one up and got the perfect measurements. I didn't have a 3d printer, so I placed an order through this business, which was very simple and easy to use! After I placed my order, It shipped 12 days earlier than expected time, and had incredible print quality. I would highly recommend this site for others looking to print high quality materials, and I would also use It again!
