Hi Lucas
I think you have a nice range of projects and a lot of nice thought process behind them as well.
I would condense the 3 separate Open Source CNC furniture projects into one. Unless there is some reason that they are different but from what I can tell feels like the same project.
Depending on the type of design role you are looking for I would say that I would like to see more process, more exploration before you reach the final solution.
What type of design job are you interested in, any specific field/product category?
