Neptune 2 / 2S bottom cover

The original cover was too tight, offering minimal ventilation and leaving little space for modifications. To resolve this, I designed a new cover that adds 10 mm of height and features ventilation holes on both sides for improved airflow. I also removed the mesh over the fan inlet to further enhance cooling.

Important: You’ll need to add feet to your machine—resting it directly on the cover will block airflow and reduce cooling performance. The cover is printed as a single piece, so make sure your 3D printer has a sufficient build volume. Note that the N2 and N2S printers are not large enough to accommodate this design on their build plates.
