The original machines have a metal box where all the electronics are stored in. It’s quite basic and easy to make, especially since you are already working with metal. However, it takes quite some time to build.
An easier and quicker quicker way to make the box is to laser cut it on 3mm plywood, which also lowers the chances of short circuits. Bear in mind that this is more expensive than doing it by yourself. Each face of the box is laser cut and connected with some nut and bolts, super simple. We've also added mounting holes for all the electronics inside the drawing which makes it easy and quick to connect everything in the right place. The laser cut parts can leave quite some rough burn-marks, we recommend to sand them when you receive them, looks way better.
