2 plates: This might mean that the print job includes two separate plates or objects that will be printed. Each plate could be a different part or a single part with two different configurations.

5 h: This stands for 5 hours, which is the estimated print time for completing the job.

0.4 mm: This could be the nozzle size of the 3D printer, which affects the detail and speed of the print. A 0.4mm nozzle is a common size that provides a good balance between detail and print speed.

139 g: This is the estimated amount of filament required for the print job, measured in grams.

3D printing settings0.2mm layer: This refers to the thickness of each layer of filament laid down by the printer. A 0.2mm layer height is relatively standard and balances detail with print speed.

3 walls: This means the model will have three layers of outer walls or perimeters. This can improve the strength and durability of the print.

15% infill: Infill is the internal structure of the print, and 15% means the print will be filled with a grid or pattern that occupies 15% of the interior volume.
