Field notes
The workbench starts with slicer measurements and expands them into a job model covering failed attempts, labor, setup, finishing, packaging, delivery, printer allocation, maintenance, electricity, and transaction fees. It distinguishes margin from markup and provides quick checks at 20%, 30%, 40%, and 50% target margins. Jobs can be saved locally, backed up or restored, and exported as JSON or a cost-breakdown CSV.
