This is a box to hold the Pimoroni Keybow 2040 and a directly mounted 1.12" OLED display. It's held together with a couple M2 screws.
The idea of the device is a "reverse calculator", so instead of computing for you, it gives the user problems and verifies answers. It supports 4 basic operators (+, -, *, /) and 4 levels of difficulty. It also keeps track of the score. Powered by USB-C.
I've printed it with default settings using Prusa Galaxy Black PLA.
The Onshape model can be found here. The GitHub repo with the CircuitPython code is here.
