Bakeneko 80 - Open source tenkeyless keyboard
« on: Sat, 23 May 2020, 10:12:30 »
A simple TKL for DIYers. This project includes PCB, case and plate. All of them are shared as open source.

  • Acrylic sandwich case.
  • POM plate. Metal plates such as brass can be selected as an option.
  • EVA plate foam. (if possible...)
  • Less functionality. No LEDs and no underglow. Minimal layout support.
  • 7 degrees typing angle.
  • QMK Firmware ready.

I'm currently building and evaluating a prototype.

PCB and case are still work in progress. Do not use the files on github for manufacturing until the first version is released.


Case and plate (WIP)


GB or sell it?
I have no plans to organize group buy or to sell extras. I'm not going to limit anyone doing them. Anyone can freely use the files in this project under an open source license.

Top Layer Dimensions

Acrylic sandwich cases are commonplace, but there are still a few things to consider especially for beginners like me.

  • The size of some parts was decided based on the key unit. I tried several combinations and picked one that seemed beautiful to me.
  • I think that the thickness of the outer frame should be at least about 0.5u (9.5-10mm) to secure the strength of acrylic.
  • 0.25u part inside the frame looks fragile, but it does not matter when used as a keyboard.
  • Top layer has a thickness of 7.5mm for a better appearance. The switch is hidden in the top layer and keycap. When the thickness was 6mm, the switch housing was visible through the gap between the cap and the top layer.



Here are the mistakes I made in my first prototype. I should have had extra space in the switch area, but I didn't. If there is no extra space, it will be difficult to insert the keycap puller. And in my opinion, the extra space makes it look more beautiful, especially if you want to highlight the brass plate's presence.
