The ByranTK-Alpha is an 80 key custom mechanical keyboard, designed to be made with any material.
"All the keys you need and no more."
The ByranTK-Alpha is an ongoing open-source keyboard project. It is extremely simple and utilizes a nice!nano from Nice Keyboards as the MCU. The battery life is estimated to be around 3 months of continuous usage (varies extremely depending on battery capacity, tested with 500mah battery from Adafruit). The keyboard is designed in KiCAD and FreeCAD, with the renders made with Blender.
Because nobody has done such thing yet. I have always wanted a simple-looking, customizable (software-wise and hardware-wise), exploded 75% layout keyboard. In addition, it had to be under a certain price point. I estimate for it to cost less than 100 dollars for all the parts and all the machining, though that is subject to change. If you want CNC alu, then that'll cost you a couple cold hard Benjamins (tldr; a lot).
(subject to change as design alters)
Note that these part links are only for reference. Some products can be found for cheaper (especially the hotswap sockets).
The SPDT and SPST switches have specific footprints that match on the board. You can alter them if they're out of stock.
You don't need to buy diodes if you are using SMT assembly. I used JLCPCB.

* The nice!nano v2 is used in this design. It has 3 extra pins in the center of the PCB, two of which the ByranTK-Alpha utilizes
