To accommodate a display centered on one open side of the rectangular housing, you'll need to modify the 3D model so that the display side has an open frame. I'll provide an STL description that maintains the 3:4:3 ratio, with an open side that would support a centered display occupying the majority of that side.

Assumptions:

• The display will be centered and take up 80% of the open side (length and width).
• We'll assume the side being opened is the largest (length by width), leaving a frame on each edge.

Here's an updated STL with the open side:

Explanation:

• The back face (which will contain the display opening) is defined with a frame by leaving a border around the centered display.
• The centered display frame measures 80% of the full dimensions of the back face, providing an even border on all four sides.
• Adjust the frame size to fit your specific display requirements by changing the inner border values.
