This is a chopped down version of my large workstation. It will accept an Arduino Uno & 400pt Breadboard. I would recommend printing at 101-102% of scale to counter shrinkage, and the Arduino mount is exact.
The feet I print in TPU, the holes will likely need bored out a bit from printing overages, I used an 1/8" bit.
I've also included an even more chopped down version for just the Arduino Uno.
The author remixed this model.
