I have a design I want to 3D print. It's tiny, less than 1 inch, and has more than one fitted, moveable part. I'd like to figure out if it's feasible before I decide whether I buy in. I don't know what software is used to make the designs. (A friend told me his printer supports .stl files) I can probably find a service that will print my design(s), though I don't know how many iterations it might take to get it right. If anyone is of a mind I'd like to pick their brains about getting the software, using the software, even digitizing my design from sketch, and specs of what I can expect (in the way of tolerance and fit, etc.) or even printing it for me. Any of the above. I'll elaborate with a sketch shortly, but meanwhile, any takers?
