Questions buyers ask first
Something else? Ask in the quote form. It's free and there's no obligation.
Will you sign an NDA?
Yes. We can sign your NDA, or send you ours, before you share any details. Mention it in the quote form and we will send it first.
Who owns the files and the design?
You do. Once the invoice is paid, all files, designs and intellectual property belong to you. We may show renders of the finished design in our portfolio and ads, but never your files or drawings, and never if you opt out or the project is under NDA.
How do revisions work?
Each package includes a set number of revision rounds. A round is one batch of changes within the agreed scope. If you change the scope, we quote the difference before doing any extra work.
What are the payment terms?
Smaller jobs are paid upfront. Larger projects are 50% to start and 50% on delivery. We accept card and bank transfer, in USD, with an invoice for every payment.
How fast is turnaround?
Typical turnaround is 48 to 72 hours from quote approval. You get a firm delivery date with your quote. Working to a tight deadline? Tell us in the form and we will say upfront whether we can hit it.
What do you need from me?
Anything that describes the part: a sketch with rough dimensions, photos with a ruler or caliper in frame, an old drawing, or existing CAD. If you know the material and how it will be made, include that too.
Do you provide stamped drawings or structural work?
We don't provide stamped or sealed drawings. We design mechanical parts, products and enclosures for manufacturing, and don't take on structural, building or permit work.
