Gyroid: 3D Print Tracker

Gyroid is the logbook for your whole 3D-printing bench. Track what is left on every spool, what each print really cost, the settings that worked, and when each printer is due for maintenance. Any brand, fully offline, no account. FILAMENT INVENTORY Grams remaining, cost, brand, colour, storage location and dry status for every spool. Group the inventory by shelf or dry box so you know which one to walk to. Log a print and the filament comes off the spool automatically. Put a spool on a kitchen scale, type the reading, and Gyroid does the tare maths, remembering core weights you name and reuse. Low-filament flags warn you before a roll runs out mid-print, with the reorder link you saved right there. Once a spool has a few prints behind it, Gyroid tells you how many more it will last at your pace. PRINT YOUR OWN SPOOL LABELS Generate QR labels for your shelf and print them from your iPhone. Stick one on each roll: scanning it opens that spool in Gyroid, from the app or straight from the Camera app. No subscription, no label service, no account. THE PRINT LOG Model, printer, filament used, the settings that worked, success or failure, a photo, and the real cost. All searchable later, so "what did I do the last time this worked" takes seconds instead of an evening. WHAT A PRINT ACTUALLY COSTS Filament, electricity, machine depreciation, optional labour and a failure allowance, combined into one number per print. Multi-colour prints record every spool they used, each charged at its own price, with power and wear counted once. The same engine powers the free calculators on our website. Sold a print? Note what it went for, and Bench stats turns cost into revenue, profit and margin, and ranks the models worth printing again. MAINTENANCE BY PRINT-HOURS Nozzle, belt and lubrication reminders are scheduled by each printer's real print-hours. Logging a print advances the clock for you. ANY PRINTER, ANY BRAND Not tied to one manufacturer's cloud or account. Track two FDM machines and a resin printer side by side, each with its own history, schedule and settings. DROP IN A SLICER FILE Open a G-code or 3MF export from your slicer and the entry pre-fills itself: model name, print time, grams, material. Two taps and it is logged. ON YOUR WRIST AND HOME SCREEN Filament and maintenance widgets, an Apple Watch app with complications, a Live Activity for the print that is running, Siri shortcuts, and Spotlight search across your prints and spools. LEARN AT THE BENCH Original troubleshooting, print-settings and material guides are built in and readable offline, right next to the printer.
