OREO Leonardo pro mini case

thingiverse

I'm using my Leonardo Pro-Mini Arduino to create a stealthy setup that looks like an Oreo with a USB lead sticking out. These little boards are great at mimicking mouse and keyboard actions, but I wanted something more discreet than the usual suspects. To keep my screen from locking up every 2 minutes and logging me off the VPN, I'm using my board to "tap" the Windows key repeatedly. It's a clever hack that saves me a lot of hassle. For this project, I used some 3mm PLA filament to create pins that hold the three parts together. It works like a charm, and I can use either a USB adapter or a short USB cable with it. The OREO case started out as a design from Thingiverse (thing:462350), which I modified to make it 45mm in diameter, just like a real Oreo. I also hollowed out the middle to fit my board snugly inside.
