The author remixed this model.
Edit3 Core One Plus Version. Not tested, please let me know.
Edit2: I have added a light version.
Edit. Gcode for quick testing.
I really like the idea of Jürgen's Core One Automatic Chamber Vent. Simple but effective.
The only thing I didn't like so much was the Nexdruder's lever.
That's why I modified the original Prusa right-hand cover to control the lever on the grid.
You can find the rest of the parts on Jürgen's original page.
Since I used the same dimensions, you can take the start Gcode from there, but as Jürgen also suggests, it should be checked manually before the first start.
