Additional thumb keys for ZSA Voyager keyboard

These keycaps are meant to fit the ZSA Voyager keyboard to allow for more thumb keys.

The default configuration for the Voyager keyboard only has 2 thumb keys on each side. I found that too limiting, so by eliminating the number row, all the alpha keys can be shifted one layer up, leaving the bottom-most layer available to be used as thumb keys (the CVBNM, keys on the default layout).  However, the innermost keys of that layer and the small thumb-cluster keys interfere with each other.

By using these custom keycaps, you can now press those keys with the thumb without interfering with the neighboring keys and allows for full set of 5 thumb keys on each side of the keyboard.

I printed vertically for better quality, with 0.10mm layer height, in galaxy black prusament PLA. Worked great. The vertical printing with low layer height gave a nice texture to the key surface. The part that had the supports needed a little cleaning, but it's the least visible part of the key once mounted, so it works great.

Adapted to fit a specific use case in the ZSA Voyager keyboard.
