Good question. The STL file is somehow scaled wrong or drawn in units of
feet or even yards or something.
Even when I load it in FreeCAD with the units set to inches, the part
comes out with dimensions like 0.1205 inches on the longest side, which
is ridiculous.
Measuring a real cover:
The main rectangle is 77.7mm x 57.8mm
Maybe you can figure out how to scale the model correctly based on that
to get all the other dims.
If you're drawing a new model from scratch, a 40-pin ribbon cable is
51mm wide, make the slot whatever you want based off that starting point.
There's no immediate lip or other obstruction on the edge of the opening
where the ribbon cable needs to come out, so the notch for the cable
doesn't have to be any particular depth. 3 or more mm should be fine.
The two rear tabs (not on the side with the finger pull)
4.04mm wide each, 59.9 mm apart inside edge to inside, 3.0mm stick out,
1.6mm thick, resting on the bottom (inside) surface not extending the
main flat rectangle.
The front tabs, on the side with the finger pull
6.06mm wide each, 43.85mm apart inside edge to inside edge
The hook part is complicated to describe without a drawing. The part
that hooks in front only sticks out about 0.5mm and starts about 1.3mm
off the bottom (inside) surface of the main flat part.
