A replacement bottom cover for the T430 but without mounting screws. I kept the airflow hole pattern from the original, but the original also had some tape bent over them perhaps to stop water ingestion? So you might want to put them on if you desire.
This model is designed to be printed with a 0.4mm nozzle at 0.3mm layer height, and these settings are very much recommended for the clips to clip on properly.
The author marked this model as their own original creation.
