SpoolNest: Filament Tracker

SpoolNest is a focused filament notebook for FDM 3D printer owners. Keep your spool weights, materials, prices and print usage together, with no account required. YOUR FILAMENT LIBRARY Add a name, colour, material, brand, storage note, original net filament weight and price. See remaining grams and spools with less than 100 g at a glance. Enter your own three-letter currency code for each spool. LOG COMPLETED PRINTS Record the filament used, including supports and purge waste. SpoolNest subtracts that weight and keeps a history for the spool. Undo the latest log if you make a mistake, or calibrate the remaining weight manually. PLAN YOUR NEXT PRINT Check whether a selected spool has enough material. Estimate filament and electricity cost using your own duration, average printer power and electricity rate. Estimates do not change your stock and exclude labour, machine wear, tax and failed prints. KEEP A COPY Records stay on your device. Export and restore JSON backups through Android's file picker. Automatic cloud backup is disabled, so export before moving devices or uninstalling. SpoolNest uses manual entries. It does not connect to your printer, read spool tags or measure weight automatically. Core tools work offline; an AdMob banner uses an internet connection when available.
