Print time estimator

Get a rough idea of how long a model will take to print, and how much filament it needs, before you slice it. Your slicer gives the exact figure; this is for deciding whether a print fits your evening.

Print speed is the main speed in your slicer, usually the infill speed. Walls print slower; that's allowed for. A 0.4 mm nozzle normally uses a 0.42 to 0.45 mm line width.
