Calisto 2 and a half alternate Dierya keyboard -- parts A and B.

This is intended to allow people to build new instances of the [Calisto 2 and a Half](https://www.thingiverse.com/thing:6643913) project. It's a wonderful project, but the 3 keyboards options for the build are either no-longer available (Dierya and GIM), or are very expensive and difficult to find (ISY). This project aims to adapt the Dierya DK63N keyboard tray to allow for the use of the Dierya DK63 in it's place, since it is still widely available (as of March 2025) ([Amazon](https://www.amazon.com/DIERYA-T63-Mechanical-Bluetooth-Typist-Black/dp/B0CP5NTTKL/ref=asc_df_B0CP5NTTKL), other sources will be be added as I find them). This can probably be adapted to other keyboards as well, though the core design won't allow for keyboards much wider than the DK63 without fundamentally reworking the A & B parts. The version in purple with the black keyboard is version 8, but the version in space-gray wth the white keybaord is the final version (10.1) I plan on producing. The source file
