Spool 3D Print Cost Calculator

• Bambu Lab X2D — new printers in the catalog • Merge prints: select several prints when importing from the cloud and get one project where every print becomes a plate • Batch tracking: a spool is a purchase batch with its own price. Bought more? Duplicate creates a new record with the new price • Archive: empty spools disappear from lists while project history and calculations stay unchanged • Grouping: batches of the same plastic collapse into one card with combined remaining and a price range — in the list and in the archive • Protected calculations: the price of a spool with print history is locked, deleting is replaced by archiving • Bambu sync: several identical cloud spools merge into one record with the summed remaining, new spools arrive with their actual remaining • "Missing from Cloud" section: you decide whether spools deleted from the Bambu library leave your stock • The plate filament picker shows price and remaining for every batch Fixes: • The plate's Add Filament button now explains what to do when you have no filaments yet • Cloud spool names no longer duplicate the material • A spool only links to a filament of its own colour • Print history import picks a batch that still has stock
