The whole shop floor, with numbers attached.

If your part does not fit one of these envelopes, we would rather you found that out here than after a week of email.

Before you send a print

CAD formats accepted
STEP, IGES, Parasolid, SolidWorks, and 2D PDF with dimensions
Minimum order
One piece. Prototypes are normal work here, not a favour
Quote turnaround
Two business days for most parts, same day for repeats
Typical lead time
10 – 15 business days for a first article, 5 – 10 for repeats
Material certification
Available on request; state it on the RFQ so we buy to certificate
Inspection report
First-article dimensional report included on every new part number

What a dimensioned print tells us

A solid model plus a print with tolerances called out where they matter is the fastest route to an accurate quote. If everything on the drawing carries the same tight tolerance, we will ask which features actually need it — loosening one dimension often takes real money off the price.
