Filament Cost & Inventory

$1.99 · Designed for iPad. Not verified for macOS.

Track filament by spool, estimate job cost and depletion, log drying, and keep material settings offline. Spoolwright is a private 3D-printing spool desk for makers who want clear filament inventory, job cost, and depletion estimates without another cloud account. Add spools by material, color, grams remaining, cost, lot note, dryer status, and favorite settings. The workbench estimates whether a spool can finish a job, material cost, energy estimate, markup, and remaining grams after the run. A built-in reference library covers humidity, dry-box notes, material changes, nozzle settings, and recordkeeping habits. KEY FEATURES - Spool inventory by material and color - Print job material and cost estimates - Depletion forecast before a long run - Dryer and humidity log - Material settings reference cards - Local PDF print sheet - 60-card offline 3D printing reference library - No account, ads, tracking, analytics, subscription, or network requirement Spoolwright is an organizer and estimator based on values you enter. It does not connect to a printer, validate G-code, or replace manufacturer guidance.
