MicroMacro Mechanical Keyboard

thingiverse

The MicroMacro is a 1% mechanical keyboard built around a cheap ATTiny85 microcontroller, complete with an Arduino profile you can configure to print whatever you want. I originally bought some Digispark boards on Aliexpress to prototype a modular keyboard system, but I made a detour to create a 1% keyboard. The current software for the MicroMacro is available at GitHub. It's based on the DigiKeyboard library for now, but my dream is to pare down the tmk_firmware to fit on an ATTiny so that all custom keyboards I make can be run on the same software. This might be a 1% keyboard, but I couldn't resist adding in some extra features. The SCAD file supports an arbitrary number of switches - you just need to increase the width and change the switch_hole_iterations! You can turn this off by setting switch_hole_iterations to 0.
