Raspberry Pi 4B case

Yet another Raspberry Pi 4B case, bit this one is all OpenSCAD so you can easily modify it from the particular versions I printed. This is all snap together parts which seem to work.

My board arrived, and I've now made major revisions and updated the files to make a case you can actually fit the board into (more useful that way).

Lots of details available at: https://tomhorsley.com/hardware/solidoodle/solidoodle-pi4b.html

Most of the design was around the cad model of the board I downloaded from grabcad
(and it seems to be a good model because the actual board fit the design).

Note that there are some utility modules in the openscad for things like an alternate 75mm VESA mount to union with the case bottom rather than the one I'm using with magnets. There is also a plain case top available for putting a 40mm fan hole rather than the overkill I have (or even just a ventilation grill and no fan).

Since I got the board to actually fit, I'm calling this done. Maybe removing the work in progress flag will get thingiverse to update the stl previews :-).
