I needed to place the display of my Elegoo Neptune 3 Pro on the left side. Therefore, I drew an adapter for the original mount. I printed it out of black PLA.
Required Parts:
6 pcs M4 nut
3 pcs M4x10 screws
3 pcs original M4 screws
Assembly:
Push 3 pcs M4 nuts into the hexagonal holes on the adapter.
Screw the adapter onto the aluminum profile of the 3D printer using suitable stones. I used only M4 nuts. It is completely sufficient.
Screw the cover and mount to the adapter using the original screws.
