Update: works with Firmware Version 6.5.3, my impression is the autovent works a little smoother now.

The testfile has to be renamed to .gcode and works for the CoreOne+ but is your own responsibility.

The stock top cover of the enclosed version of the mmu3 with the blop has different vent openings like the acryl version. So i had to design a new Version of the slide stick. I used a test program to open and close the grille and it seems to work perfectly. You have to add the printhead mod from the CoreOne+ upgrade at Prusa printable parts. You can use the stock screws and the -ugly- knobs on the outside. Then you activate it in the hardware section of settings menu by turning it to ‚auto‘. Best prints in 30% infill gyroid with black Prusament PC-Blend (looks like the grille)

BUT: this is not an official Prusa part so i'm not responsible for any harm to your printer so here is the DISCLAIMER: if you using this mod it is your responsibilty anything fits together. Also you are responsible for start and end g-code mods and any damage there might occur.

If you want to fix the problem that the firmware doesn' t put the vent in the right position at every start here is a solution from the forum:
