Split ergonomic custom mechanical keyboard with handy thumb buttons. The Redox is a smaller, simplified remix of the classic Ergodox with fewer keys but just as much comfort. It's easy to make, inexpensive, and looks great in any filament.

The Redox is a great first keyboard project - it's easy to print, easy to build, and runs the free and easy-to-configure QMK firmware. The 1u version is especially interesting, because you only need to buy one size of keycap for the entire board!

Configure and download firmware at https://config.qmk.fm/#/redox/rev1/LAYOUT

Print one BottomL and one BottomR. Then, print PlateL1u and PlateR1u OR PlateL and PlateR. The 1u versions use only 1-unit-wide keycaps, which makes the board smaller and reduces the number of differently sized keycaps you need to buy. Otherwise, the two are identical.
