Every feature we ship
is on this page.
Built by makers, in the open. Every item below was requested in the forum, voted up, and shipped.
Spool Inspector hardware
Filament scale + QR scanner. Drop a spool on, scan the code, you're logged. Drying timer and on-device location selection built in.
AI photo identification
Snap a label or box. Brand, material, color, density, and recommended bed/nozzle temps populate automatically.
2,000+ filament catalog
Every brand variant the community has contributed — diameter, density, recommended temps, drying schedules, and empty-spool tare weights all on file. Pick a brand and color; the rest fills itself in.
Bambu Lab integration
Connect your Bambu Cloud account. Live AMS slot loadouts on the dashboard, print history linked back to the spools each job actually used.
Panda Breath integration
Pair a Panda Breath dryer over Wi-Fi via captive portal. Live heater state, set point, and chamber temperature on your dashboard — connected drying without juggling another app and controlled over the web without requiring LAN mode.
Project-based cost tracking
Tie weighings to projects. Cards break down real cost for Filament (gram-accurate from your actual rolls) + Finishing (hardware, glue) + Machine (hourly rate × print time). Real cost, not a slicer guess.
Slicer import
Drag a .gcode or .3mf from Bambu Studio onto the prints page. Plates, materials, AMS slot assignments, estimated grams + print time all auto-extract.
Burn rate predictions
“You have 12 days of black PLA left at your current pace.” Per-material trend lines learned from your weighing history, surfaced before you run out.
Label printing
Niimbot B-series, Phomemo, Dymo Connect , and Avery sheet labels — pick whichever you own. Every label includes a QR that the Spool Inspector can scan.
Color wall
Visual swatch grid of every distinct color you own, grouped by material. “Do I have that translucent green?” answered in one glance.
Public REST API
/api/v1/spools, /api/v1/usage, /api/v1/projects — paginated, key-authenticated, scoped to your data. Build your own dashboards or pipe into your existing tooling.
Mobile-first workflow
Photo-ID a stack of new spools in the workshop with your phone. Sit down at the desktop and sheet-print all the labels in one pass. Every screen works on a phone — the inventory, the weighing flow, the project costs, all of it.
