Layerline: 3D Print Calculator

Layerline is the all-in-one 3D printing toolkit for makers, hobbyists and print farms. Price every print with an accurate 3D print cost calculator, track filament stock spool by spool, run calibration maths with ready-to-send G-code, and keep a print log that learns from every failure. Works with any FDM 3D printer and every common filament: PLA, PETG, ABS, ASA, TPU, nylon and carbon-fibre blends.

★ 3D PRINT COST CALCULATOR
Get a real quote in seconds, not a guess.
• Pick your country: 20 regions fill in currency, electricity price per kWh, filament price per kg and labour rate automatically
• 18 printer presets with typical power draw, price and lifetime, or use your own printers
• Filament cost, electricity cost, machine wear (depreciation), labour, parts and a failure buffer, all broken down on a clear receipt
• Supports and purge, heat inserts and magnets, paint and finishing, packaging, tax / VAT
• Profit margin, price per piece and price per gram for selling on Etsy or your own shop
• Save quotes and share them with customers

★ FILAMENT TRACKER & SPOOL INVENTORY
• See grams left on every spool at a glance, with low-stock alerts
• Spool weight calculator: weigh the spool, subtract the empty spool, get grams and metres of filament left
• Filament length calculator for 1.75 mm and 2.85 mm
• Value of your filament stock, filtered by material
• Logging a print takes the used filament off the spool automatically

★ 3D PRINTER CALIBRATION CALCULATORS
Eight calibration tools with formulas, before / after comparison and copy-ready G-code:
• E-steps calculator (M92)
• Klipper rotation distance
• Flow rate / extrusion multiplier
• Shrinkage and XY dimensional accuracy
• Pressure advance / linear advance (M900, Klipper)
• Retraction tower
• Temperature tower
• Max volumetric flow and print speed limit
Save results to a calibration history so you can roll back any change.

★ PRINT LOG & PRINT TRACKER
• Log successful and failed prints with time, grams, cost and notes
• Track live progress and time left on the print that is running
• Record failure reasons (spaghetti, warping, bed adhesion, clogs, layer shifts…) and how far the print got
• Success rate, total print hours, filament used and money wasted on failures

★ MACHINE GARAGE & MAINTENANCE
• Running cost per hour for each 3D printer
• Hour meter fed by your print log
• Maintenance reminders: nozzle swap, belt tension, rod lubrication, bed levelling, build plate cleaning, plus your own jobs

WHY MAKERS USE LAYERLINE
• Works offline. Your data stays on your phone, with no account and no sign-up
• Designed for real workshops: a bold dark interface built around print beds, spools and G-code
• Useful for beginners learning to calibrate a first printer and for small businesses pricing 3D printed parts
