## What is Nozzlebook?

Nozzlebook is the calm, simple 3D printing companion for your 3D printer. Track every filament spool, see what each print really costs in filament and electricity, and get a notification the moment your print finishes.

PRINT TIMER & ALERTS

• Notification when it's done, plus an optional heads-up 5–30 minutes before
• Slicer too optimistic? Add 15 minutes or an hour and the alerts move with it
• Home Screen and Lock Screen widgets show time left at a glance

TRUE COST OF EVERY PRINT
• Filament cost from your spool's price per gram
• Electricity cost from your printer's wattage and your kWh rate
• Machine wear spread over your printer's lifetime

• PLA, PETG, ABS, ASA, TPU, nylon, PC, carbon fiber blends and more

PRINTERS & MAINTENANCE LOG
