Description

PDF

This is a case that fits a Raspberry Pi 4B, 3.5 inch GPIO TFT screen, and 40mm fan. It mounts to the side of an Elegoo Neptune 3 Pro in place of the original screen using the original screws.

The top of the case is unmodified from the original, but provided for convenience.

When printing the bottom of the case, I recommend painting supports at the bottom of the vertex of the mounting side (See pictures).

Differences of the remix compared to the original

I modified the bottom of the original case to allow mounting on an Elegoo Neptune 3 Pro in place of the original screen. I mounted using the original screws. The ribbon cable hole has also been moved the the back-left of the case.
