Layerbook: 3D Print Calculator

Layerbook is an offline 3D printing calculator for FDM printer owners. Use it to price print jobs, calibrate your printer, and keep track of how much filament is left on every spool. It works fully offline, with no account and no ads.

3D PRINT COST CALCULATOR & QUOTES
━━━━━━━━━━━━━━━━━━━━
Work out what a print actually costs before you quote or sell it. Layerbook adds up:
- Filament cost from grams or metres, using your spool price and weight
- Electricity from your printer's power draw and your tariff per kWh
- Machine wear, based on printer price, maintenance and expected lifetime
- Labour time and post-processing costs
- A failure-rate buffer, markup and optional tax

You see a clear breakdown of every cost, plus a per-unit and total price for any quantity. Jobs can use more than one filament. Save jobs, search them by client or printer, duplicate them for repeat orders, and share a clean PDF or text quote.

GUIDED PRINTER CALIBRATION
━━━━━━━━━━━━━━━━━━━━
Step-by-step wizards explain what to measure and calculate the new value for you:
- E-steps calibration for Marlin printers
- Rotation distance calibration for Klipper
- Flow rate calibration from measured wall thickness
- Shrinkage and dimensional compensation from a calibration cube
- Tower value finder for temperature, retraction and speed towers
- Max print speed from your volumetric flow limit
- Z "magic number" layer heights based on your lead screw and stepper motor

Apply a result directly to your printer profile. Every run is saved to that printer's calibration history with old and new values.

━━━━━━━━━━━━━━━━━━━━
FILAMENT SPOOL TRACKER
━━━━━━━━━━━━━━━━━━━━
Weigh a spool, enter the weight, and Layerbook subtracts the empty spool to show remaining filament in grams and metres. Keep a weigh-in history for each spool, mark spools as sealed, in use or empty, and check whether there is enough filament left for a saved job before you start printing.

━━━━━━━━━━━━━━━━━━━━
PRINTER & FILAMENT PROFILES
━━━━━━━━━━━━━━━━━━━━
- Save printers with nozzle size, power draw, firmware type and calibration values
- Save filaments with material, diameter, density, spool price and spool weight
- Editable density presets for PLA, PETG, ABS, ASA, TPU, Nylon, PC and PLA-CF
- 1.75 mm, 2.85 mm and custom filament diameters

━━━━━━━━━━━━━━━━━━━━
QUICK CONVERTERS
━━━━━━━━━━━━━━━━━━━━
- Filament weight to length, and length to weight
- Millimetres to inches
- Celsius to Fahrenheit

━━━━━━━━━━━━━━━━━━━━
WHO IT'S FOR
━━━━━━━━━━━━━━━━━━━━
- Hobbyists tuning a new or upgraded printer
- Makers selling prints online or at markets
- Small print farms pricing orders consistently
- Makerspaces, schools and workshops

━━━━━━━━━━━━━━━━━━━━
PRIVATE AND OFFLINE
━━━━━━━━━━━━━━━━━━━━
- Works without an internet connection
- No sign-up, no account and no ads
- No data collected or shared; everything stays on your device
- Back up and restore all your data with a single file you control
- Light and dark themes, dynamic colour, and layouts for phones and tablets

Set your currency and electricity tariff once, add your printer and filaments, and Layerbook keeps your print costs, calibration values and spool stock in one place.

Calibration results are calculated from the measurements you enter. Check values against your printer's documentation before applying them.
