/gcode — G-code Viewer
Open a sliced 3D-printer G-code file and see the toolpath layer by layer, with print time and filament use estimates. Nothing uploaded.

The time estimate is naive — distance divided by the commanded feedrate, with no acceleration, jerk or heat-up. Real prints take longer; the slicer's own estimate is shown next to it when the file carries one.
Working out spool cost or leftover length instead? Use the filament calculator. Want to see the model rather than the sliced output? Open it in the 3D model viewer.
