Spool — 3D Printing Queue & Filament Tracker

Spool — 3D Printing Queue & Filament Tracker — a premium, 100% offline digital tool by Aceplore. Runs entirely in your browser: no accounts, no subscriptions, your data never leaves your device.

A private, offline command centre for your printers — the queue, every spool, real cost per print, maintenance, calibration and a failure log that tells you why it keeps happening.

28 built-in tools in one app. A live print queue with a print log and per-printer time and utilisation; a spool inventory with remaining grams, a running-low list, usage history, a drying log, storage locations, a to-buy list and a material reference for PLA, PETG, ABS, ASA, TPU and nylon; a printer register with a maintenance schedule, a calibration record and slicer profiles; a real cost-per-print model combining filament by weight, electricity by kWh, machine depreciation, failure allowance and labour, a quick estimate, a customer quote and a spend view; a failure log with a troubleshooting reference and a success-rate breakdown by printer, material and model; a model library with licence tracking; plus reports, CSV/JSON export and settings.

Queue, Spool Inventory & Usage. A queue and print log per printer, plus a spool inventory that decrements real grams as you log prints, flags spools running low, records drying and storage, and builds a to-buy list automatically.

Cost Per Print & Quote. Filament by weight, electricity by kWh and print hours, machine depreciation, a failure allowance and your labour rate — combined into a true unit cost, a quick estimate and a customer-ready quote.

Failure Log, Troubleshooting & Maintenance. Log every failure with a cause and the wasted grams, get a success rate broken down by printer, material and model, work through a troubleshooting reference, and keep maintenance and calibration on a schedule.

Spool is a planning, costing and organization tool for makers. Every quantity, layout and price it reports is computed to a standard published formula from the numbers you enter — an estimate to plan with, not a guarantee of a result. Materials vary, machines vary and hands vary: always measure your own stock and cut a test piece before committing your good material, and follow the safety guidance for every tool and material you use. Costing figures are a pricing aid, not business, tax or legal advice. You are solely responsible for your own making and selling decisions.
