Portable monitor stand

Just a simple stand for my portable monitor so that it doesn’t fall over all the time when I want to use it on the train. I included a hollow version as well to reduce filament usage and printing time. It could be useful to add some kind of anti-slip material to the bottom. I haven’t had too much of a problem with it yet, but it could definitely help. Printing shouldn’t be too much of a problem. It’s just a pyramid after all.
