The price on upload is the price you pay.

the problem

UK print shops are quote-by-email by design. Two days for a quote, two more for a tweak, twenty-piece minimums. Offshore is cheaper but unpredictable: held at customs, shipping damage, no one accountable.

the discipline

Three commitments, architectural not aspirational: no quote-by-email, no minimum order, UK end-to-end. The Python pipeline is the operator: quote, queue, print, QC, dispatch, comms.

the output

A part dispatched with its own job ticket: process, material lot, parameters, QC pass. The customer can repeat-order an identical part without an engineer in the loop.
