Summary

Add a proper SpoolType entity to track different spool types and their weights per manufacturer.

Upstream Issue

https://github.com/Donkie/Spoolman/issues/567 (3 👍)
Note: Donkie declined this, but we want it!

Problem

Manufacturers use different spool types with different weights:

Plastic spool: ~250g
Cardboard spool: ~175g
Metal/reusable: ~300g
Masterspool/refill: ~0g

Current workarounds:

Create duplicate manufacturers ("ERYONE" vs "ERYONE [Cardboard]")
Manually adjust spool weight every time
Lose spool type metadata after import from SpoolmanDB

Proposed Solution

Data Model

class SpoolType(Base):
    id: int
    name: str  # "Plastic", "Cardboard", "Metal", "Masterspool"
    vendor_id: Optional[int]  # Vendor-specific spool type
    weight: float  # Empty spool weight in grams
    description: str

class Vendor(Base):
    # existing fields...
    default_spool_type_id: Optional[int]  # Default for this vendor

class Filament(Base):
    # existing fields...
    spool_type_id: Optional[int]  # Override vendor default

Features

Global spool types - Plastic, Cardboard, Metal with standard weights
Vendor-specific types - ERYONE Cardboard (175g), Bambu Cardboard (145g)
Default per vendor - ERYONE defaults to Cardboard
Override per filament - This specific filament uses different spool
Import from SpoolmanDB - Preserve spool_type from external DB

UI

SpoolType management in Settings
Dropdown in filament create/edit
Show spool type in filament list
Auto-calculate empty weight based on type

Data Source

Printables has a spool weight catalog that could be referenced.
