Hey Ben I Have been tinkering with the Raspberry Pi circuit board when I came across your youtube channel. The first video I watched was you're second briefcase 3D Printer. It occurred to me that there are some linux cad programs out there. Why don't you take out the step of having to create a design using an external computer and have the Raspberry Pi on board directly connected to the 3d printer. Like an all in one. I would love to see a detailed video of how you would do it.
