I am a hobbyist. Usually if I see it I can build it. I work with electronics, prototyping, molding and casting, 3d printing, some 3d designing for parts. I have built all of my printers so that I can know them better. I love working on group projects and I am willing to work directly with some one if they need to sit down and make prints as they make changes. I have very cheep rates on printing small Items start at $15 after that we will work on time and price of how much the filament cost. If the part that is needed printed is a medical part there is no cost unless it would be for the filament and I buy it when its on-sale and free shipping so its less than $15.
