FAQ
Before you send a part.
Other questions: add them to the quote form.
I only have a rough idea. Is that enough to start?
Yes. A description, sketch or photo of something similar is enough to scope and quote.
Do I need CAD files?
No. If you have them, send STEP or STL and we'll review, refine or prototype from them.
Who owns the design?
You do. On completion and payment, the design files are yours.
Is my idea kept confidential?
Yes. All enquiries are confidential. On request, we sign an NDA before you share details. Tick the NDA box in the quote form.
What does a prototype cost?
It depends on size, complexity and design work. Quotes are free and fixed, and agreed before work starts.
Is there a minimum order?
No. One part or a short run.
