Filament Depot: 3D Spool Log

Filament Depot is a clean, Apple-Health–inspired iOS app for makers who print a lot. Track every filament spool you own as a colour ring with remaining filament at a glance — log usage as you print, follow price changes across vendors, and never run out mid-job.

THE WALL — VISUAL INVENTORY

Every spool gets its own concentric colour ring. The colour is the filament; the ring's thickness is what's left. Search by name or brand, filter by material, sort by lowest-first to instantly spot what needs reordering.

LOG USAGE WITHOUT FRICTION

Tap a spool, enter grams used, see exactly what's left after this print. Quick-pick buttons for 10, 25, 50, 100, 200g. Optional confirmation step you can switch off once you trust the flow.

PRICE-AWARE TOP-UPS

Every purchase is logged as a lot — its own date, price, and vendor. The Purchase History card shows your last paid price, your weighted average per kilogram, and the % change vs your previous lot. A new top-up that's more than 0.5% off the last price triggers an alert; above 10%, it warns you to double-check the vendor before saving.
