Post script for generating metadata displayed on Ender 3 V3 SE in PrusaSlicer. Written and tested on Ender 3 V3 SE. This script adds information to gcode file needed for preview menu to display filament used, layer height and print time.

1. Install python
2. Copy the EnderV3PrusaPreviewData.py to any location. For example: C:\Users\Username\AppData\Roaming\PrusaSlicer\scripts\EnderV3PrusaPreviewData.py
3. In PrusaSlicer go to PrintSettings -> OutputOptions -> Post-processing scripts and paste link to your python installation directory and file. For example: C:\Users\Username\AppData\Local\Programs\Python\Python312\python.exe C:\Users\Username\AppData\Roaming\PrusaSlicer\scripts\EnderV3PrusaPreviewData.py;

Your slicer will then automatically run the script after each time you save gcode file to enrich it with additional data.
