Raspberry Pi 4 plus Geekworm X862

Details
---------

Using two of the files from the Raspberry Pi 4 case from John Sinclair (specifically the V3_lower and Pi_Case_Upper_solid files), I modified these to be able to hold a RPi4 with a Suptronics X862 daughterboard and an M.2 drive.

Modifications to the original design include:
- Top:
- Moved the standoffs in the case top slightly to align with the RPi4.
- Lengthened 1.5mm to match the bottom. This was stretched, not properly edited.
- Bottom
- Lengthened 1.5mm to accommodate the X862. This was edited, not stretched, so no distortions.
- Redesigned to be taller. (Again edited, not stretched)
- Add a hole for the X862 USB jack
- Modified holes for screws to accept flat head countersunk M2.5 screws
- Created 'bump-out' to accommodate the X862
- Closed up the SD Card slot (booting from X862 attached drive; no SD card)

The modification work was done in Tinkercad. I am still new to 3D print CAD, so there are obvious issues with my modificatio
