Fairphone 4 case has hole on the bottom

[x3e]

The pre-generated Fairphone 4 case seems to have a hole on the bottom. Is that what it is supposed to look like? I'm trying to understand if there is supposed to be a cap or cover that goes over this hole.

(Sadly I noticed this only after I had started the print. Oh well...)

After careful inspection, I think the hole should not be there. I fixed it by setting _ELECTRONICS_CUTAWAY_LENGTH=24; (instead of 25) and:

module electronicsCutaway() {
    union() {
        color("pink")
        translate([-_ELECTRONICS_CUTAWAY_WIDTH/2, -PHONE_KEYBOARD_OVERLAP-_ELECTRONICS_BAY_TOPWALL_THICKNESS-_ELECTRONICS_CUTAWAY_LENGTH, -PHONE_THICKNESS/2+0.01+_ELECTRONICS_CUTAWAY_BACKWALL_EXTRAPERIMETERS*EXTRUSION_WIDTH])
        difference() {
            cube(size=[_ELECTRONICS_CUTAWAY_WIDTH, _ELECTRONICS_CUTAWAY_LENGTH, _ELECTRONICS_CUTAWAY_THICKNESS], center=false);
            translate([0,0,_ELECTRONICS_CUTAWAY_THICKNESS/2]) rotate([-90-45,0,0]) cube([1000,1000,1000]);
        }
    }
}

That way, I don't have to increase the outer dimensions. I just hope the electronics still fit.

Here is mine:

The hole seems in nature to be bigger than in the drawing. But I think that the reason for the hole is that sound waves from the speaker and to the microphone require a way where its possible to pass the case...

Ah that might be the reason. I printed it without a bottom hole and the audio sounds fine. I don't know about the microphone, I take the keyboard off for phone calls.

Sorry for the late reply. The hole shouldn't be there, x3e's fix is a good one.

In my experience, the keyboard case lets more than enough sound through and at least on my FP4 and my Samsung A54, the bottom-firing speaker actually sounds better with the keyboard on. Boosts the base a bit and redirects the sound more to the front.

I usually take the keyboard off for phone calls too, but people tell me that it doesn't make an audible difference. Unless if I am typing during a call, that apparently sounds horrible.
