A useful price, with the assumptions attached
SpoolMargin is operated and maintained by Dheeraj Namburu. Its guides explain the same calculation model used by the workbench, using explicitly illustrative inputs rather than claims of printer testing or verified market prices. SpoolMargin helps makers price an order without losing sight of their material, machine time, labor, fulfillment, and fee assumptions. It is a calculator, not a verified price database or a quoting service.
The workbench offers batch pricing, illustrative starting points, slicer metadata preview, local saved jobs, versioned JSON backups, CSV cost breakdowns, internal printable reports, and post-job reconciliation.
