Neptune 2 / 2s bottom cover

The original cover is very tight, providing minimal ventilation and leaving little room for modifications without causing space issues. To address this, I designed a new cover that adds 10mm in height and includes breathing holes on both sides to improve airflow. Additionally, I removed the mesh that previously covered the fan inlet for better ventilation.

Please note, you’ll need to add feet to your machine because resting it directly on the cover will block airflow and impair cooling. The cover is printed as a single piece, so you will need a 3D printer with a large enough build volume to accommodate it; the N2 or N2S printers are not big enough to fit this design on their bed plates.
