Field notes
The tool list extends beyond the headline checker and cost calculator: it includes filament length-to-weight conversion, a part-used spool calculator, resin costing, and a density chart. The site says its guides and calculators use the same dated dataset, and it labels print-time estimates as ±20% rather than presenting them as exact. The extracted page describes these features but does not show their interactive operation.
