Spool Pantry

Spool Pantry is the filament inventory app for 3D printing enthusiasts. Whether you have a handful of spools or a wall full of them, Spool Pantry keeps everything organized so you always know what you have, where it is, and how much is left.

TRACK EVERY SPOOL
Log brand, material, color, diameter, weight, purchase date, price, and notes. Add a photo so you can identify spools at a glance. A low-stock warning flags spools running below 15% so you can reorder before you run out mid-print.

SEE YOUR INVENTORY AT A GLANCE
The Storage view shows your spools arranged on visual shelves — just like your actual rack. Drag spools between shelves to keep things organized. The Filaments tab gives you a searchable, sortable list grouped by material type.

TRACK WHAT'S LOADED
Add your printers and load spools onto them with a tap. Spool Pantry shows you exactly what's on each machine, and unloading a spool returns it to its original shelf automatically.

SYNCS ACROSS ALL YOUR DEVICES
Your inventory lives in your personal iCloud account and syncs seamlessly between your iPhone and iPad. No account to create, no subscription, no servers — your data is yours.
