Post Description

Hello, something I built for fun - a sandbox where you can play around with conveyor belts, pneumatic tubes and boxes. A bit like marble run. You can toggle to dev mode to drag things around, add new elements, delete them. I guess you can also type out the config manually (they're not that complex). You can also save configs as text files and re-upload them to load.
