Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

Teased a month ago, Ok-March1037 aka DreaM117er shared the design files and a build log of his Explorer RxCT (this cryptic latter part of the name stands for "Row x Column and Thumb keys").

This modular board was inspired by projects like BastardKB's TBK Mini, the 5x6 Dactyl Manuform, atsuyukis DM Skeleton Edition, and also by James Sa's Pragmatic resources.
