About this app

Spool Hoarder is a filament inventory and project tracker for 3D printing. Know what you own, how much is left on every spool, where it is stored, and what each print actually costs.

Scan a label, log a print, and your inventory updates itself.

ORGANIZE YOUR FILAMENT

• Track brand, material, color, remaining weight, price, storage location, and print settings for every spool


• Search, sort, group, and filter by brand, material, color, location, or your own tags


• Favorite the spools you reach for most so they stay at the top


• Remaining weights stay current as you record usage, so you always know what is really left

ADD SPOOLS IN SECONDS

• Photograph a spool label and let AI fill in the details


• Batch scan several spools in one session


• Scan supported UPC barcodes and NFC tags for instant identification


• Works with compatible OpenSpool, Bambu Lab, Prusa, and OpenTag3D tags


• Use the built-in AI scanning or bring your own API key

PLAN PRINTS AND TRACK USAGE

• Create projects and assign the filament you plan to use


• Record the grams actually consumed after each print


• Spool inventory updates automatically when usage is logged


• Estimate material and overhead cost before you hit print


• Share a "What I Used" card when a project is finished

FIND BETTER COLOR COMBINATIONS

• Color Advisor suggests complementary pairings from the filament you already own


• Holiday Palette turns up seasonal combinations


• Search the open SpoolmanDB catalog for known brands, materials, and colors

UNDERSTAND YOUR INVENTORY

• See inventory value, spending, material usage, consumption trends, and low-stock alerts


• Tap any statistic to jump straight to the spools or projects behind it

KEEP CONTROL OF YOUR DATA

• Automatic rolling backups plus one-tap manual backups
