SpoolPainter V2 Release

SpoolPainter v2

Complete rebuild of SpoolPainter — Android app for managing 3D printer filament spools with NFC tags and a self-hosted Spoolman server.

Highlights

• Create vendor + filament + spool in Spoolman by filling the form and tapping a blank tag — all in one motion. Custom Material, Brand, Color (with swatches), and
  temperature ranges.
• Edit Variant on existing spools — type a new variant on a spool you already paired, Spoolman gets PATCHed alongside the tag write.
• Pair a second tag to the same spool — two-sided spools land both UIDs on one Spoolman entry.
• Move-on-bind — retag a spool, old tags cleared automatically. No orphan UIDs hanging around.
• Filament metadata expander — density, diameter, weight, spool weight, price; reads from Spoolman, edits PATCH back.
• NFC status pills at top of screen — "Reading…" / "Writing…" so you always know what state the tap is in.
• Vendor tag awareness (Bambu, Creality, Snapmaker, TigerTag) — detected and UID-paired with a Spoolman spool. Content decoding lands in v2.1.
• Side modes — Raw write (write a payload to a blank tag without binding to Spoolman) and Vendor UID-only pair.
• Auto-cleanup of orphan Spoolman records when a Save & Write fails partway through.
• Spoolman gating — form sections hide entirely when no URL is configured, disable when configured but offline. The temperature section stays usable in all states
  because temps live on the tag, not Spoolman.
• Settings: independent sort orders for spool dropdown (Material/Brand/ID/Last Used) + filament picker, Light/Dark theme toggle, currency selector ($/€/¤),
  keyboard-aware snackbars.
