The last and best thing that I designed was a base that raises the printer giving the fan more air flow while providing a place to mount the RPi that hosts NanoDLP.
I did some other designs as well:
Spatula based on the one that comes with the printer.
Device to help me level the build plate.
Handles 'cause mine did not have one and the damn thing is slippery.
Feet to raise the printer for better airflow.
