Online 3d software apps are horrid

you want use mm NOT inches.
also have a look at Openscad - things like that are doable in minutes and it only outputs fully manifold printable models.

I also don't see any holes in the case for you to plug stuff into the board. is that deliberate ?

How big is it ? if convert directly from mm to inches its 11.7 inches by 6.26 by 2.14
That's pretty big for a pi case.

@Curious Aardvark, in an earlier post, there are electronic modules (more than one) mounted in the model. I suspect the dimensions you reference may be close, although I paid little attention to that aspect.

L=5 1/2in
W=6 1/4in
H=1 13/16in

all measuring is using ruler and caliper measuring in Inches.
As for holes, i want to build the enclosure first and then do the holes once the erros are ironed out.

So in the STL there is 2 items: 1 is the lid, and the second is the enclosure itself. For whatever reason Meshmixer read both pieces as one build.
