Know exactly what you need? Even better.
A lot of people hesitate to reach out because they think they are supposed to arrive with a spec. Material, tolerance, file format, method. You do not need any of that.
What you can send us is simple. A photo of the object. A sentence about what you want to do with it. Whether you have any existing drawing or none at all. That is enough for us to understand the job.
From there, the figuring-out is our job. We tell you what the object needs, what the deliverable should be, and what it costs. Whether you know the answer already or have no idea, it is nothing to worry about. That is exactly what we are here for.
