Splitkb Kyria case (rev1, 2 and 3)

A case for the Kyria keyboard, with about 15° of tent and 8° of negative tilt.

That's what worked best for me, but Fusion 360 f3d file included if you want to change these angles.

Tested with a rev2 board, but should work with all since it uses holes that didn't move between rev2 and 3.

Extra hardware for the two halves:

• 6 M2x10 screws (head no larger than 4.2mm)
• 8 rubber feet (holes designed for 13mm diameter ones, but stick any other ones anywhere else)

The bottom plate screws right onto three spacers. Keep the original case's bottom plate, and just remove the three M2x5 screws, replacing them with the M2x10 that screw in through the inner poles.
