FEATURED / 01
Scale a model without breaking proportions
Set one target dimension and get the exact uniform percentage for your slicer.
THE WORKBENCH / 10 TOOLS
Pick the calculation you need
Each tool has focused inputs, transparent assumptions, and no account wall.
Geometry
Model scale and dimension calculator
Scale STL dimensions proportionally, find a scale percentage, and check final X, Y, and Z sizes before slicing.
Layer count and print height calculator
Calculate full layers, final print height, and remainder from model height, layer height, and optional first-layer height.
Nozzle, line width, and wall planner
Plan line width, wall count, resulting wall thickness, and gap against a target FDM shell thickness.
Materials
Filament weight, length, and cost calculator
Convert 3D printer filament between weight and length and estimate material cost by diameter, density, and spool price.
Resin volume and cost calculator
Estimate resin print volume, mass, bottle usage, and material cost with configurable density, waste, and price.
Extrusion
Extrusion flow rate calculator
Calculate deposited cross-section, volumetric extrusion flow, filament feed rate, and mass flow for an FDM move.
E-steps calibration calculator
Calculate corrected extruder steps per millimeter from commanded, measured, and current E-steps values.
Volumetric flow limit calculator
Convert a tested volumetric flow ceiling into a maximum print speed for selected line width and layer height.
Planning & inspection
Print time comparison calculator
Compare two 3D print durations, percentage change, time saved, throughput, and optional machine-cost difference.
Local G-code summary analyzer
Inspect a G-code file locally for commands, layers, bounds, extrusion, temperatures, tools, and slicer metadata without uploading it.
LOCAL BY DESIGN
Your files and measurements stay at your workbench.
Every calculation runs in this browser. Even the G-code analyzer reads the selected file locally—there is no upload endpoint, account, or retained job history.
